Résumé :

In order to obtain better vibration suppression effect, this paper designs a semiactive/fully active hybrid isolator by using magnetorheological elastomer (MRE) and piezoelectric material. Combined with multimode control scheme, full frequency vibration suppression is achieved. Firstly, series type structure is determined for the hybrid isolator, and the structure of hybrid isolator is designed. Next, the dynamic model of hybrid isolator is derived, the dynamic characteristics measurement for MRE isolator and piezoelectric stack actuator (PSA) is established, and parameters such as voltage-displacement coefficient, stiffness and damping constant are identified from the experimental results, respectively. Meanwhile, the switch frequency is determined by experimental results of PSA and MRE isolator. Lastly, influence of the stiffness of MRE, control voltage of PSA, and intermediate mass on hybrid isolator system is analyzed by simulations, and the results show that the hybrid isolator proposed is effective.

Résumé :

This work is generally aimed to synthesize POSS based BCPs via RAFT polymerization, to study their self-assembly behaviors, to research on the effect of POSS self-assembly structure on the bulk properties and to prepare nanostructured hybrid epoxy via self-assembly of POSS based copolymer. In Chapter1, We studied the RAFT polymerization of POSS macromers and capable to synthesize well defined POSS based BCPs with high POSS fraction and different topology such as AB，BAB and (BA)3. The vertex group and the morphology effect on thermo-mechanical properties of POSS based BCPs as well as the structure-property relationship was investigated. Dispersion RAFT polymerization in apolar solvent was applied and various aggregates with different morphology in Chapter2. Cooling induced reversible micelle formation and transition was found and the pathway selection in vesicle formation was investigated. Nano-construction of O/I hybrid epoxy materials based on POSS based copolymers was investigated in Chapter4. The effect of functional group content on miscibility of POSS based statistic copolymer and epoxy was investigated. A novel method to nanostructure epoxy hybrid involving self-assembly of POSS based BCPs in epoxy was presented. High homogeneity and well size/morphology control of core-corona structure containing rigid POSS core and soluble PMMA corona in networks were obtained.

Résumé :

In recent years, several groups have investigated the changes of chemical and physical properties of materials with size in the nanometer scale. These studies have highlighted a number of possible applications for nanostructures, which are now employed, for example, in biology and medicine for imaging, disease detection, diagnosis, sensing and therapy. In noble metals, the coherent collective oscillation of electrons in the conduction band (Surface Plasmon Resonance, SPR), induces large surface electric fields which greatly enhance the radiative properties of gold and silver NPs when they interact with resonant electromagnetic radiation. The coupling of SPR with the electromagnetic field may lead to a huge enhancement of both the absorption and scattering cross sections. The SPR, tunable in the visible (for spherical gold NPs) and near-infrared region (for anisotropic gold NPs) of the electromagnetic spectrum, can also interact, with the fluorescence emission of dyes and substantially modify their brightness and excited-state lifetime. One of the considerations that has inspired the present project is the expect that any change in the dielectric constant of the NP surface, induced, for example, by a biorecognition process that occurs on the surface itself, can produce a change in the emission properties of the fluorophores. SPR effect becomes also important when combined with two-photon excitation (TPE), which consists in the simultaneous absorption of two photons, each carrying about half the energy necessary to excite the molecule. In fact, the luminescence (TPL) induced by TPE is enhanced (when coupled with an appropriate plasmon resonance) by many orders of magnitude in gold nanorods respect to a standard fluorophore. These properties promise to improve the usefulness of these nanoparticles for in-vivo imaging in the NIR region of the electromagnetic spectrum and have inspired the second part of the project. The aim of the first part has been studied the interaction of gold nanoparticles a few nanometers in size with fluorophores and to exploit the changes of the dye excited-state lifetime and brightness induced by our interaction in solution under physiological conditions. I have investigated the system based on 5 and 10 nm gold NPs coupled (via a biotin-streptavidin linker) to a fluorophore (FITC) and to a specific protein antibody. The binding of protein to the gold NPs through antigen-antibody recognition modifies the dye excited-state lifetime, which change can then be used to measure the protein concentration. In particular, we have tested the nanodevice measuring the change of the fluorophore excited-state lifetime after the binding of the model protein bovine serum albumine (BSA) and p53 protein, a marker for early cancer diagnosis and prognosis (both in standard solution and in total cell extracts). These studies have been published in {J. Phys. Chem. C 2009 113(7) 2722-2730} and {J. Biom. Nanotech. 2009 5 683-691}. In the second part of the project I focused on the use of anisotropic gold nanoparticles as probe in cellular imaging. I have studied the optical properties of gold nanorods synthesized with standard surfactant CTAB (cetyl trimethylammonium bromide) and asymmetric branched gold nanoparticles synthesized with zwitterionic surfactant LSB (laurylsulphobetaine). The sample have been analyzed with a number of structural techniques to obtain a complete characterization: absortpion spectra, TEM images, Fluorescence Correlation Spectroscopy (FCS) and Dynamic Light Scattering (DLS) experiments in suspensions. From the analysis of the data, I have gained information on the nanoparticles shapes, dimension and aggregation numbers. In particular, three different populations have been found: nanospheres with diameter lower than 20 nm, nanostars characterized by large trapezoidal branches, and asymmetric branced nanoparticles with high aspect ratio (≈ 4-5) (published {Chem. Comm., 2011; 47; 1315-1317}). Moreover, TPL (two-photon luminescence) was finally exploited to study by optical microscopy the problems of internalization and toxicity of gold nanoparticles by different cell line (macrophages, HEK and A549). Presently, is in preparation a manuscript on TPL, cellular uptake and cytotoxicity of branched gold NPs. In the last year I have demonstrated the potential use of NPs, gold nanorods and magnetic nanoparticles (MNPs), as a novel contrast reagent for selective thermal therapy of cancer cells using a near-infrared low energy laser and an AC magnetic field, respectively. Photothermal therapy for cancer have been widely investigated as a minimally invasive treatment modality in comparison with other methods. The appeal of gold NRs as contrast agents is amplified by their additional capability to absorb photons and to convert into heat by nonradiative processes (phonon-phonon interaction). Magnetic nanoparticles heat inductively due to magnetic losses associated with three mechanisms: hysteresis, N\'eel relaxation and Brownian relaxation; moreover they are considered as a low toxicity material with gold and biological compatibility. These two kinds of NPs (gold and magnetic nanoparticles) are delivered to cancer cells and heated to induce apoptosis (programmed cell death). Within this last part of the project, I have first evaluated the increase in temperature of NR and MNP solutions, using a direct visualization by means of a sensitive thermocamera. Then I have developed a nano-sensor to measure the local temperature on the surface of the nanoparticles under excitation. The rationale is to bind an organic chromophore whose excited state lifetime (ESLT) is particularly sensitive to the temperature, and to refer to its lifetime which is an intensive parameter. Rhodamine B is such a fluorophore, with a temperature dependence of the excited state lifetime ≈ 0.029 ± 0.001 ns/°C, as we also measure here. Moreover this nanoconstruct can target tissues or single cells and used for imaging before the therapy. Part of these experimental results have been successfully composed to numerical simulations of light induced heating of gold nanorods, using the Two Temperature Model (TTM) in order to calculate raising in temperature due to laser irradiation. Finally, I have developed methods and knowledge in the field of the use of NPs made of gold or oxide ({Nanotoxicology, 2011; doi:10.3109/17435390}) in biological and medical research and applications. These studies have produced four publications and two additional manuscripts are under preparation on the cytotoxicity of these NPs and their use for imaging and phototherapy.

Résumé :

Le but de la Nano- Opto- Mécanique et Electronic à base de graphène est d'utiliser des membranes de graphène en suspension comme blocs de construction pour aborder le couplage entre l'optique, la mécanique et l'électronique dans ce nouveau matériau. Avec un module d'Young similaire à celui du diamant (1 TPA), le graphène est une membrane extrêmement rigide, légère et mince (epaaisseur de seulement un atome) qui peut supporter son propre poids sans effondrement ou la rupture lorsqu'il est suspendu. Ces membranes, intégrées dans des dispositifs mécaniques, peuvent être actionnés à partir de DC jusqu'à des fréquences de vibration mécaniques très élevées (GHz). En outre, le graphène est un gaz d'électrons 2D exposé pour lequel une porte électrostatique tunes considérablement la densité de porteurs de charge et ses propriétés optiques. Last but not least, il offre une architecture unique pour effectuer la fonctionnalisation physico-chimiques et obtenir des matériaux hybrides combinant les propriétés particulières des espèces chimisorbées avec ceux du graphène
The aim of the Graphene Nano- Opto- Mechanics and Electronics is to use suspended graphene membranes as building blocks to address the coupling of optics, mechanics and electronics in this novel material. With a Young modulus similar to that of diamond (1 TPa), graphene is an extremely stiff, light and atomically thin membrane that can withstand its own weight without collapsing or breaking when suspended. Such membranes, integrated as mechanical devices, can be actuated from DC up to very high mechanical vibration frequencies (GHz). Moreover, graphene is an exposed 2D electron gas for which an electrostatic gate dramatically tunes the charge carrier density and its optical properties. Last but not least, it provides a unique architecture to perform physico-chemical functionalization and obtain hybrid materials combining the peculiar properties of adsorbed and chemisorbed species with the graphene ones

Résumé :

Following the modern lines of development in theranostic field, this PhD research project focuses mainly on the field of oncological therapies where the primary purpose of the research is to increase the effectiveness of treatments and to decrease the undesirable toxic side effects of current therapies, which indiscriminately affect both sick and healthy cells, causing often serious collateral damages. The goal can be achieved by creating biocompatible smart systems that do not require carriers to function, but that are themselves able to "move" recognize and treat diseased tissues. The research project proposes the development of new organic/inorganic hybrid nanosystems having a core-shell-shell structure, consisting of nanoparticles (NPs) (Au and/or Fe3O4@Au) in which PEGylate porphyrin systems are bounded. The choice of synthesizing these hybrid systems, stems from the possibility of exploiting the different properties of the individual components, combined into a single complex system. The gold nanoparticles were chosen for the different properties in the theranostic field. AuNPs are considered to be relatively biologically non-reactive and therefore suitable for in vivo applications. Other advantageous qualities include the strong optical properties of AuNPs due to localized surface plasmon resonance (LSPR), easily controllable surface chemistry which enables versatility in adding surface functional groups, and lastly, the ease in control over particle size and shape during synthesis. Silver nanoparticles (AgNPs) are increasingly being investigated as tools for novel cancer therapeutics, capitalizing on their unique properties to enhance potential therapeutic efficacy. The AgNPs are a promising tool as anticancer agents in diagnostics and probing, with strong effects against different cancer cell lines offering many advantages. Their better penetration, and the possibility to track AgNPs in the body make them a more efficient tool in cancer treatment with less risk compared to standard therapeutic procedures. The unique AgNP properties, such as easy surface functionalization, optical properties, reproducible synthetic routes and high surface: volume ratio, makes them suitable for cancer treatment. The optical properties can be tuned to have an absorption at specific wavelengths that is useful for imaging and photothermal applications in tissue. The magnetite core will provide the paramagnetic properties necessary for use in the Targeted Drug Delivery (NPs tissues via magnetic field), in Magnetic Resonance Imaging and Magnetic Hyperthermia (the magnetic NPs may be subjected to an alternating magnetic field, overheating and thus determining cell death). The nanoscale dimensions of the complex system (40-100 nm) will allow the latter to perform passive targeting (EPR effect), while the external shell obtained by functionalization with the PEGylated porphyrins derivatives will induce the necessary water solubility and biocompatibility of the whole system. Given the excellent absorption spectroscopic properties, fluorescence (to monitor its presence inside the tissues) and photo-cytotoxicity (for the photodynamic therapy of tumors), it will be possible to strongly implement the field of application and efficiency of these nanohybrid systems. In synthesis, upon validation of the functioning of the system, the synthesis strategy can be adapted to functionalize and/or co-functionalize the nanoparticles also with active targeting agents to limit the accumulation exclusively in diseased tissues endowed with specific receptors, further implementing the targeting properties described above. Therefore, the results obtained during my PhD research work, could be a fundamental starting point in order to developing systems for theranostic applications, exploiting both the nanoparticles and the porphyrin derivatives properties, thus to obtain multifunctional platforms for biomedical applications.

Résumé :

This thesis describes the preparation and characterization of core-shell noble metal-magnetite hybrid hollow nanocomposites utilizing hierarchical architecture. The hollow magnetite (hFe3O4) nanoparticles were prepared by hydrothermal method, forming the cavity via Oswald ripening. Further surface modifications involved both inorganic and organic coatings, conferring the intracellular drug delivery ability and the catalytic enhancement. In the first part, a series of hierarchical core-shell nanostructures flower-like hFe3O4@AlOOH was synthesized through solvothermal method and sol-gel process. The formation of cavity accessible hFe3O4@γ-AlOOH was achieved using silica-templated solvothermal treatment where the Kirkendall effect was observed. The morphologies of the as-prepared nanocomposites were characterized by scanning electron microscope (SEM), transmission electron microscope (TEM), dynamic light scattering (DLS), thermogravimetric analysis (TGA) and Fourier-transform infrared spectroscopy (FTIR). Then, the nano-encapsulation of platinum drug using hollow magnetite and its derivatives, has been developed with improved loading efficiency via co-solvent system. A dimethylformamide/water co-solvent system was found to be the most efficient system to encapsulate water-insoluble cisplatin. The platinum content was further quantitatively and qualitatively analyzed by inductively coupled plasma mass spectrometry (ICP-MS) and FTIR spectroscopy. The enhancement of loading efficiency could be driven by emulsification due to the diffusion of hydrophobic cisplatin into the hollow cavity of iron oxide nanoparticles. By incorporating water, the loading efficiency of hFe3O4 and hFe3O4@γ-AlOOH increased from 1-2% to 27% and from 6% to 54%, respectively. The grafting of cisplatin on AlOOH nanoflakes might account for the high loading efficiency of flower-like hFe3O4@AlOOH. As a complement to naked hFe3O4, a cell-penetrating poly(disulfide)s (CPD)-decorated hollow iron oxide nanoparticle was synthesized by immobilizing both cysteine and MPTMS as an initiator, followed by in situ polymerization to form hFe3O4-Cys-CPD-CONH2 and hFe3O4-MPS-CPD-CONH2. The morphologies were characterized by TEM/energy-dispersive X-ray spectroscopy (TEM/EDX) and the compositions of the as-prepared iron oxide nanocomposites were characterized by TGA, FTIR and X-ray photoelectron spectroscopy (XPS) and ICP-MS. The CPD coating not only serve as a protective layer, but also prevent the encapsulated cisplatin from a premature release. The hFe3O4-MPS-CPD-CONH2 exhibit promising features for the intracellular delivery of cisplatin, demonstrating a glutathione (GSH)-responsive drug release. Comparing with other hFe3O4 nanoparticles, an enhancement of cellular uptake of hFe3O4-MPS-CPD-CONH2 could be observed by optical microscope, showing rapid accumulation of the hFe3O4-MPS-CPD-CONH2 nanocomposites in the primary human renal proximal tubular epithelial cells (HRPTEpiCs) cell in 2 h. At 24 h, hFe3O4 (F), hFe3O4-MPS (FS) and hFe3O4-MPS-CPD-CONH2 (FSC) together with cisplatin treatment did not cause any significant cytotoxicity to the cells when the particle concentration is less than 10 µg/mL. Interestingly, FSCC showed a certain extent of toxicity with increasing Fe and Pt concentration along with the treated time. It may suggest that the hFe3O4-MPS-CPD-CONH2 nanoparticle, as a cisplatin carrier, could enhance the drug efficiency by increasing cellular uptake of the nanoparticles in HRPTEpiCs together with the boosted cytotoxicity. Based on these data, cisplatin- hFe3O4-MPS-CPD-CONH2 (FSCC) treatments with the concentration less than 20 µg/mL and duration no more than 24 h could maintain around 70% of the cell viability of the HRPTEpiCs. The hypothesis, at which CPD serves as an efficient carrier for intracellular cisplatin delivery, could be confirmed by both microscopic images and the cell viability test. In the second part, a series of Au/Fe3O4 hybrid nanocomposites was prepared to investigate their catalytic efficiencies using 4-nitrophenol reduction as a model system. The flower-like hFe3O4@γ-AlOOH@SiO2-NH2@Au was prepared by using protonated ammonium on hFe3O4@γ-AlOOH@SiO2-NH2 to entangle gold nanoparticles (AuNPs) via electrostatic attraction. In comparison to numerous of catalytic studies, the turnover frequency (TOF) of hFe3O4@γ-AlOOH@SiO2-NH2@Au shows a superior conversion rate up to 7.57 min-1 (4-nitrophenol per Au per min) for the 4-nitrophenol using sodium borohydride as a reductant. A rapid conversion of 4-nitrohpenol was observed using flower like composites that converted the 4-nitrophenol within 2 min. Our result suggests that silica residue hinders the reduction rate of the 4-nitrophenol. A significant deviation from pseudo first order was observed for densely AuNPs-functionalized nanoflower system, hFe3O4@γ-AlOOH@SiO2-NH2@Au2X, which is different from most of the 4-nitrophenol reductions reported in literature. The hFe3O4@γ-AlOOH@SiO2-NH2@Au also demonstrates catalytic activity when heated up to 800 °C before reduction. The recyclability was examined using magnetically recycled hFe3O4@γ-AlOOH@SiO2-NH2@Au, which showed insignificant decrease in the catalytic efficiency. To prove the concept, platinum nanoparticles (PtNPs) immobilized hFe3O4@γ-AlOOH@SiO2-NH2@Pt and hFe3O4@γ-AlOOH@SiO2-NH2@Pt/Au were also prepared via electrostatic attraction to verify the feasibility of endowing modular functionality via post modification.

Résumé :

DNA computing is a branch of biomolecular computing using the physical and chemical properties of deoxyribonucleic acid or DNA. It is a fast-developing interdisciplinary research area consisting of nano-biotechnology, computer science and biochemistry. DNA computing is widely used now-a-days for logic design, biomarker, cryptography, disease detection etc. In recent years, carbon nanotube or CNT research has reached a new peak with its various applications including nano-biocomputing. DNA plays a pivotal role in biology and CNT is considered as a wonder material of this century in nanoscience. This chapter combines these two promising research areas including CNT and DNA to form CNT-DNA based nanostructured system and its applications in diverse fields like electronics, biomedical engineering, drug delivery, gene therapy, biosensor technology etc. CNT-DNA hybrid and its various suitable combinations open up a new dimension called CNT-DNA computing.

Résumé :

Tissue engineering may require precise patterning of cells and bioactive factors to recreate the complex, 3D architecture of native tissue. These cells and bioactive components may then need to be repositioned during tissue growth in vitro and noninvasively imaged to track tissue development. We developed a new hybrid nano-bioprinting system by combining the initial patterning capabilities of a direct cell writing system with the active patterning capabilities of superparamagnetic nanoparticles. The iron oxide nanoparticles can be conjugated with proteins or loaded inside cells, printed into computer-defined patterns, and then manipulated and imaged within the 3D tissue engineering construct. In this study, iron oxide nanoparticles were bioprinted either in an alginate scaffold or inside endothelial cells. Cell viability, patterning, and imaging were assessed.

Résumé :

The rapid prototyping (RP) technology has been advanced for various applications such as verification of design, functional test. Recently, researchers have studied various materials to fabricate functional RP parts. In this research, a nano composite deposition system (NCDS), which can fabricate various nano composites using polymer resins with various nano particles, was introduced. The NCDS is a hybrid system in which material removal process by mechanical micro machining and/or the deposition process is combined. To predict the mechanical behavior of nano composite part made by NCDS, it is critical to understand the mechanical properties of the NCDS material. The NCDS process was characterizes by process parameters such as raster orientation, bead width, weight percent, and curing condition. Tensile strengths and compressive strengths of fabricated specimens with various raster orientation were measured, and various sample parts made of nano composites were fabricated using NCDS.

Résumé :

Inclusion of nano-sized alumina by the surface treatment of S2 fiberglass (fiber modification) or ultrasonically exfoliated in epoxy resin system (resin modification) has been shown to provide epoxy-fiberglass hybrid composite systems with changes in their mechanical/ damage behavior under static tensile loading conditions. Integration of alumina nano-particles in epoxy-S2 fiberglass to form hybrid composites has not only shown improvements in the material properties, but also changes in the failure mechanism of the material system. This phenomenon is influenced by the changes in constituent interaction and its load transfer mechanism. In the processing of these hybrids composite systems, alumina nano-particles (sized at 110nm) are functionalized and grafted into epoxy composite material system during material processing via resin solution treatment and fabric surface treatment. These alumina embedding methodologies to form hybrid composites employed are the resin modification and fiber modification in conjunction with the conventional vacuum assisted resin transfer molding (VARTM) process for the manufacture of composite laminates. The chemical bonding and adhesion between the inorganic alumina and the organic resin is also enhanced via the functional treatment of the alumina particles with a coupling agent in the form of tris-2-methyoxyethoxy vinylsilane- T2MEVS (silane coupling agent). Processing methodologies are used to fabricate particulate reinforcement for various (<5%wt) compositions. Performance evaluation is carried to study the effect of the nano-particulate alumina on mechanical properties. Thermo-physical properties changes caused by particulate inclusion in hybrid material matrix phase are studied via Differential Scanning Calorimetry (DSC) and are also discussed.
