Texto completoReactive oxygen species (hydrogen peroxide, hydroxyl and superoxide radicals) are produced when the regulation of oxygen metabolism is disrupted. These species are directly or indirectly responsible for numerous oxidative damage at the molecular level (nucleic acids, proteins, lipids, etc.) which can affect cellular mechanisms. However, hydrogen peroxide could also behave as a secondary messenger in various signaling pathways and be the source of physiological processes. Thus its dual function has aroused the interest of many laboratories which are now trying to elucidate its role and its degree of involvement in physiological and pathological processes. In order to detect hydrogen peroxide, many pro-probes have been developed, based on a boronate trigger. Most of these probes proved able to detect an oxidative stress in cellulo but suffer from lack of reactivity. The goal of my thesis project was to improve the reactivity of the trigger by developing pro-probes with a borinate trigger. In spite of difficulties of synthesis, we obtained such a pro-probe with a borinate trigger, dissymmetrical, and bearing both a phenyl and a coumarin substituent, chosen as chromophore. Kinetic studies have shown that the reactivity of our borinate pro-probe is 100 times higher than that of the current boronate-based trigger pro-probe, under physiological conditions. A reaction mechanism has been proposed. Finally, our pro-probe has been validated in cellulo on macrophages, activated with PMA for the endogenous detection of hydrogen peroxide. Encouraged by these results, we are currently synthesizing other pro-probes with borinate trigger presenting other chromophores

Texto completoLn near-field optical microcsopy (NSOM), an active tip uses a single nanoparticle's luminescence as source of light to image a sample. Such probe should allow one to reach a lateral optical resolution only limited by the size of the particle. Implementing an active tip faces three main issues: a suitable near-field environment, and particles displaying suitable emission characteristics have to be available, and eventually those particles have to be attached at the end of a standard NSOM tip. During this thesis, a NSOM/confocal microscope designed for such applications has been developped. Imaging experiments using a single CdSe nanocrystal have been presented. Prospective studies on other particles fit for such applications are presented : doped rare-earths oxides and nanodiamonds (diameter smaller than 25 nm) doped by col or center

Texto completoNous avons développé un microscope dual confocal/NSOM adapté à l'étude et l'utilisation de telles nanoparticules. A l'aide de ce microscope, nous avons acquis des images construites en utilisant la fluorescence d'un nanocristal de CdSe/ZnSe unique (~ 4 nm) rapporté en extrémité d'une pointe NSOM normale comme source de lumière. Le caractère intermittent de cette fluorescence, combiné avec le photoblanchiment de ces nanocristaux, ont empêché de reconstruire des images complètes permettant de quantifier la résolution latérale atteinte. Notre recherche s'est ensuite portée vers la caractérisation d'autres nanoparticules dont la luminescence ne présente ni blanchiment, ni clignotement. Le premier type de particules présentant ces caractéristiques sont des agrégats de YAG :Ce3+ produits par LECBD, d'une taille inférieure à 5 nm. Nous décrivons les premières caractérisations optiques de ces nanoparticules. La seconde alternative réside dans les nanoparticules de diamant dopées avec des centres NV. Nous avons démontré que notre dispositif permet de sélectionner les nano-diamants qui sont fluorescents, de mesurer leur taille et, dans le cas des particules fluorescentes, de déterminer celles qui hébergent un seul centre NV unique dont l'état de charge est de plus déterminé in situ. Nous montrons ainsi que notre NSOM détecte aisément le centre NV unique dans une nanoparticule de diamant de 25 nm. Cette démonstration ouvre la perspective de pouvoir utiliser une telle particule mais de taille arbitrairement petite comme source de lumière.

Texto completoIn the « aperture NSOM » configuration, the optical resolution is limited to 50-100 nm in the best cases. In order to probe the optical properties of systems which exhibit dimensions at the nanoscale, a better optical resolution would be advantageous. To reach this goal, we suggest the use of an optical active probe. This kind of probe is based on a fluorescent nano-emitter grafted at the apex of a classical dielectric optical probe. The resolution expected in the optical near-field should be ultimately only limited by the size of the nano-object, that is well below 50 nm. On the basis of previous works done in our laboratory, we present here two new methods for obtaining such optical active probes. These new probes involve two complementary kinds of nanoparticles with attractive sizes and good optical properties (like high emission rate in the visible and excellent photostability). The first method implies YAG nanoparticles synthesized and deposited at the apex of a probe using LECBD (Low Energy Cluster Beam Deposition). The second approach is based on the in situ selection of a nanodiamond hosting color centers (NV) which is attached onto the tip with the help of a charged polymer. Finally, we report on the realization of a room-temperature scanning single-photon probe based on a 20 nm nanodiamond hosting a single NV center, which has been successfully used for NSOM imaging. Such tips should ultimately offer a better resolution than classical optical near-field probes, and should also open new perspectives in various fields like quantum optics/plasmonics or high-resolution, high-sensitivity magnetometry

Texto completoThe probe commonly used in aperture NSOM consists of a sub-wavelength aperture at the apex of a metal coated sharp dielectric tip, allowing to reach an optical resolution of the order of the aperture size (50 nm). A promising concept consists in replacing the aperture b a subwavelength sized active medium as small as one single molecule or semiconductor nanoparticle. In this scheme, the active probe offers the possibility to obtain a very high resolution defined by the size of the active nano-object. We have developed a method to realizl active optical tips for use in near-field optics with the goal of making photostable light nanosources working at room temperature and potentially able to offer optical resolution in the 10 nm range. A metal-coated optical tip is covered with a thin PMMA layer stained with CdSe nanocrystals or nanorods at low density. For this purpose, specially designed optical tips have been prepared using chemical etching and subsequent aluminium coating of optical fibres. They have a free optical aperture at the apex in the 200 nm range. The timeevolution of the spectral signature of the active tips together with temporal analysis of their emission rate in a photon-counting mode clearly demonstrate that a very small number of nanoparticles - possibly down to only one - are active at the tip apex for suitable CdSe dilution rates. The spectral and temporal behaviour of the active tips has been confirmed by studying the emission of single nanonanoparticle dispersed in thin PMMA films using a home-made confocal microscope. NSOM imaging of test surfaces using these active tips are in progress

Texto completoPolymeric nanoparticles have been considered to have the potential to improve drug delivery to the desired site of action and to enable delivery of poorly soluble, poorly absorbed or unstable drugs. In this work, two types of active substances have been chosen for encapsulation in polymeric nanoparticles: fluorogenic probes for intracellular targeting of the reduced glutathione (GSH), namely ortho-phthaldialdehyde (OPA) and naphthalene-2,3-dicarboxaldehyde (NDA), as well as salmon calcitonin (sCT) which is a polypeptide hormone. The probe or sCT-loaded nanoparticles were obtained using a simple or double emulsion solvent evaporation method, respectively. The obtained nanoparticles were thoroughly characterized, e.g. in terms of the size, zeta potential, encapsulation efficiency, drug (probe) release, cytotoxicity or microscopic morphology and thermal properties. NDA-loaded nanoparticles were incubated with yeast cells and intracellular NDA-GSH adduct levels increased by about 9-times in comparison with the free probe. In the case of sCT, the in vivo study was conducted in rats, and it was demonstrated that after subcutaneous injection of sCT-loaded nanoparticles, elevated serum sCT levels could be sustained for 3 days. In conclusion, the active molecules incorporated in polymeric nanoparticles achieved the better cellular uptake (NDA) and bioavailability (sCT) that the non encapsulated ones

Texto completoNucleic acids detection and quantification via electro-active probes intercalation applied to the integration of in-vitro isothermal amplification reactions. Detection and quantification of pathogenic agents through their DNA has become increasingly important in applications such as molecular diagnostics and food safety control to environmental monitoring. Routinely, these analyses are performed using optical quantitative PCR method by coupling the in vitro DNA amplification reaction PCR with fluorescent detection. However, it requires the use of a thermocycler as well as the integration of optical instrumentation leading to a bulky and expensive apparatus, unable to process turbid or colored samples. In order to circumvent these limitations, an alternative electrochemical monitoring method for PCR, based on the use of electro-active probes preferentially binding to double stranded DNA, has been proposed and developed at the LEM. A pre-industrial demonstrator developed in partnership with the start-up Easy Life Science allows the parallelization of real time electrochemical PCR measurements in a custom-made 48 wells plate. This work deals with the thermic regulation problem by replacing PCR by two alternatives isothermal DNA amplification methods. First, the LAMP (Loop Mediated Isothermal Amplification), known to be highly efficient and specific, is combined to an electrochemical detection through the use of a panel of redox probes in order to obtain analytical performances competing with the standard optical techniques. Secondly an isothermal amplification method with a simpler mechanism than LAMP, based on the recycling of the products of an HCR (Hybridization Chain Reaction), is also proposed. Finally, a new miniaturized plate integrating, to date, one hundred low volume (≤ μL) electrochemical cells as well as the corresponding potentiostat are presented. The novelty of this plate relies on its very low cost fabrication process based on the simple assembly of screen-printed films. Although the results presented were at room temperature, in the long term, it is envisioned to monitor isothermal amplification reactions in a “digital” manner
