Résumé :
Lipopolysaccharides (LPS) are endotoxins, hazardous and toxic inflammatory stimulators released from the outer membrane of Gram-negative bacteria, and are the major cause of septic shock giving rise to millions of fatal illnesses worldwide. There is an urgent need to identify and detect these molecules selectively and rapidly. Pathogen detection has been done by traditional as well as biosensor-based methods. Nanomaterial based biosensors can assist in achieving these goals and have tremendous potential. The biosensing techniques developed are low-cost, easy to operate, and give a fast response. Due to extremely small size, large surface area, and scope for surface modification, nanomaterials have been used to target various biomolecules, including LPS. The sensing mechanism can be quite complex and involves the transformation of chemical interactions into amplified physical signals. Many different sorts of nanomaterials such as metal nanomaterials, magnetic nanomaterials, quantum dots, and others have been used for biosensing of LPS and have shown attractive results. This review considers the recent developments in the application of nanomaterials in sensing of LPS with emphasis given mainly to electrochemical and optical sensing.

Résumé :
The detection of carbon dioxide (CO2) is critical for environmental monitoring, chemical safety control, and many industrial applications. The manifold application fields as well as the huge range of CO2 concentration to be measured make CO2 sensing a challenging task. Thus, the ability to reliably and quantitatively detect carbon dioxide requires vastly improved materials and approaches that can work under different environmental conditions. Due to their unique favorable chemical, optical, physical, and electrical properties, nanomaterials are considered state-of-the-art sensing materials. This mini-review documents the advancement of nanomaterial-based CO2 sensors in the last two decades and discusses their strengths, weaknesses, and major applications. The use of nanomaterials for CO2 sensing offers several improvements in terms of selectivity, sensitivity, response time, and detection, demonstrating the advantage of using nanomaterials for developing high-performance CO2 sensors. Anticipated future trends in the area of nanomaterial-based CO2 sensors are also discussed in light of the existing limitations.

Tu, Minh Hieu. « Investigation of metal nanomaterials as a sensing element in LSPR-based optical fibre sensor development ». Thesis, City University London, 2014. http://openaccess.city.ac.uk/5919/.

Texte intégral
Résumé :
This thesis aims to explore and demonstrate the potential of using optical fibres both as a waveguide material and a transducer for wide sensing applications, based on a comprehensive review of the localised surface plasmon resonance (LSPR) phenomenon, which occurs at a nanoscale level when light interacts with metallic nanoparticles at a resonance wavelength. The LSPR effect of metallic nanomaterials has shown a strong dependence on the local surrounding environment. A small change for example in the refractive index or in the solution concentration can result in a variation in the LSPR spectrum. Based on this underpinning sensing mechanism, a portable system using an optical fibre coated with gold nanoparticles (AuNPs) as a sensing probe has been developed and tested for the refractive index measurement. Coupled with this, a systematic approach has been developed and applied in this work to optimize the performance of the developed system by considering several key factors, such as the size of nanoparticles produced, pH, coating time and coating temperature. The above optimised probes coated with gold-nanoparticles are further cross-compared with those optimized but coated with gold nanorods with a high aspect ratio. Both types of probes are also prepared for a specific biosensing application based on the antibody-antigen interaction to create wavelength-based sensors for the detection of anti-human IgG. Both probes have exhibited excellent refractive index (RI) sensitivity, showing ~914 nm/RIU (refractive index unit) for the probe coated with gold nanoparticles and ~601 nm/RIU for the one coated with gold nanorods. When using the modified probes for the detection of anti-human IgG, both probes are able to achieve a good LOD (limit of detection) at 1.6 nM. Based on the above cross-comparison, further research has been undertaken to explore the potential of nanoparticles of the alloy of gold and silver, with an aim to combine the robustness of gold and the excellent LSPR effect of silver. To do so, various alloy particles with varied gold/silver ratio and sizes have been prepared and tested for their respective refractive index sensitivities. The probe coated with alloy particles with bigger size and higher silver content has shown better performance in RI sensing. The work has shown a clear relationship between the size of alloys, the content ratio of alloys and RI sensitivity. Research has also been undertaken in this thesis to explore the excellent LSPR effect of hollow nanoparticles resulting from the enhanced coupling between the interior and exterior of the hollow particles. Gold hollow nanocages have been successfully synthesised and tested with different hollowness and a LSPR sensor coated with gold nanocages has shown an excellent sensitivity as high as ~1933 nm/RIU, which is more than 3 times higher than that coated with AuNPs. This result has confirmed that a significant improvement in sensitivity can be made possible for further biosensing as well as chemical sensing applications.

Le travail décrit dans cette thèse se concentre sur le développement de matériaux « durs et mous » ainsi que leur interaction avec les cellules biologiques pour une application finale dans le domaine de la théranostique couvrant l'imagerie, la détection, la thérapie génique et la thérapie du cancer. Dans ce contexte, nous avons tout d'abord étudié l'utilisation de complexes (II) de platine phosphorescents auto-assemblés comme sonde cellulaire. Nous avons étendu l'idée de bio-imagerie en introduisant un concept d’imagerie basée sur l’émission stimulée où nous étions en mesure de générer un laser provenant d'une cellule biologique unique sans utiliser de cavité optique conventionnelle. En outre, des nano-transporteurs multifonctionnels à base de matières poreuses dures à savoir des zéolithes L et des nanoparticules de silice mésoporeuse pour de la « drug delivery » (relargage de médicaments et d’oligonucléotides) in vitro ide ont été développés avec succès et testés pour le traitement du glioblastome. Un autre nano-vecteur, qui est construit à partir de silice biodégradable, a également été synthétisé et sa capacité d'encapsuler des protéines et de les libérer dans les cellules vivantes lors de la dégradation de la structure dans un environnement réducteur a été démontrée. Enfin, l'utilisation de nouveaux matériaux plasmonique sur la base de nanoparticules d'argent enrobées de silice cassable pour la détection d'agents réducteurs a été mise en valeur
The work described in this thesis focuses on the development of soft- and hard-materials as well as their interaction with biological cells for applications in the field of theranostics covering imaging, sensing, and gene, and cancer therapy. In this context, we first investigated the use of phosphorescent self-assembled platinum(II) complexes as cellular probes. We extended the concept stimulated emission-based bioimaging by generating a laser-like emission coming from a single biological cell without using any conventional optical cavity. In addition, we successfully developed multifunctional nanocarriers based on porous hard materials, namely zeolites-L and mesoporous silica nanoparticles for drug and oligonucleotide delivery in vitro and they were tested to treat glioblastoma. Another nanovector, which is constructed from biodegradable silica, was also synthesized and its ability to encapsulate proteins and release them in living cells upon degradation of the structure in reductive environment was demonstrated. Finally, the use of novel plasmonic structures based on breakable silica-coated silver nanoparticles for detection of reducing agents was successfully investigated

Résumé :
The popularity of graphene owing to its unique properties has triggered huge interest in other two-dimensional (2D) nanomaterials. Among them, silicene shows considerable promise for electronic devices due to the expected compatibility with silicon electronics. However, the high-end potential application of silicene in electronic devices is limited owing to the lack of an energy band gap. Hence, the principal objective of this research is to tune the electronic and magnetic properties of silicene related nanomaterials through first-principles models. I first explored the impact of edge functionalization and doping on the stabilities, electronic, and magnetic properties of silicene nanoribbons (SiNRs) and revealed that the modified structures indicate remarkable spin gapless semiconductor and half-metal behaviors. In order to open and tune a band gap in silicene, SiNRs were perforated with periodic nanoholes. It was found that the band gap varies based on the nanoribbon’s width, nanohole’s repeat periodicity, and nanohole’s position due to the quantum confinement effect. To continue to take advantage of quantum confinement, I also studied the electronic and magnetic properties of hydrogenated silicene nanoflakes (SiNFs). It was discovered that half-hydrogenated SiNFs produce a large spin moment that is directly proportional to the square of the flake’s size. Next, I studied the adsorption behavior of various gas molecules on SiNRs. Based on my results, the SiNR could serve as a highly sensitive gas sensor for CO and NH3 detection and a disposable gas sensor for NO, NO2, and SO2. I also considered adsorption behavior of toxic gas molecules on boron carbide (BC3) and found that unlike graphene, BC3 has good sensitivity to the gas molecules due to the presence of active B atoms. My findings divulged the promising potential of BC3 as a highly sensitive molecular sensor for NO and NH3 detection and a catalyst for NO2 dissociation. Finally, I scrutinized the interactions of CO2 with lithium-functionalized germanene. It was discovered that although a single CO2 molecule was weakly physisorbed on pristine germanene, a significant improvement on its adsorption energy was found by utilizing Li-functionalized germanene as the adsorbent. My results suggest that Li-functionalized germanene shows promise for CO2 capture.

Résumé :
: Recently, carbon-based nanomaterials (CBNM) have been widely used for chemical and biosensing applications due to their outstanding physicochemical properties, such as mechanical, thermal, optical, electrical and structural diversity. Such materials include carbon nanotubes, graphene oxide, graphene quantum dots and fullerene. As a consequence of inimitable features, these give superior strength, electrical conductivity, and flexibility toward numerous chemical and biological objects, which is valuable for chemical sensing and biosensing purposes. However, the specific intrinsic property makes graphene and carbon nanotubes (CNTs) most attractive among the various allotropes of carbon. Since the environmental contaminants in ppm level affect the people, therefore the use of CBNM for environmental sensing provides an accessible cache of data for modelling, which makes it easy to monitor environmental challenges. Thus, the biological, chemical, thermal, stress, optical, strain and flow sensors deliver a larger surface area, excellent electrical conductivity with chemical constancy, as well as mechanical difficulty with straightforward functionalization pathways of CNTs to improve old-style carbon electrode sensor platforms. Therefore, in this chapter, the CBNM for sensing purposes are focused in detail on their mechanism.

Abstract. Structural health monitoring has proven to be a dependable source for ensuring the integrity of the structure. It also aids in detecting and estimating the progression of cracks and the loss of structural performance. The most compelling components in the structural health monitoring system are sensing material and sensor technology. In health monitoring systems, fiber optic sensors, strain gauges, temperature sensors, shape memory alloys, and other types of sensors are commonly used. Even though the sensors bring monetary value to the system, they have some apparent drawbacks. As a result, self-sensing cement composite was established as a sensor alternative with better endurance and compatibility than sensors. Carbon nanotubes, nanofibers, graphene nanoplates, and graphene oxide are carbon-based nanomaterials with unique mechanical and electrical properties. As a result, this review comprises a complete assessment of the fresh, mechanical, and electrical properties of self-sensing cement composite developed using carbon-based nanoparticles. The research also focuses on the self-monitoring performance of cement composite in concrete beams, both bulk and embedded, by graphing the deviation of fractional change in resistivity with strain. The network channel development of carbon-based nanomaterials in cement composites and their characterization acquired using scanning electron microscopy (SEM), and X-Ray diffraction spectroscopy (XRD) research are also comprehensively discussed. According to the study, increasing carbon-based embedment decreased the relative slump and flowability while increasing the composite's compressive, split tensile, flexural, and post-peak performance. Also, the amount of carbon in the carbon-based nanomaterial directly relates to the composite's conductivity. As a result, the development of piezoresistive and sensing capabilities in carbon-based self-sensing cement composites not only improves mechanical and conductive properties but also serves as a sensor in structural health monitoring of flexural members.
