Texte intégralLocalised surface plasmon resonance (LSPR) is defined as the collective oscillation of the conduction electron cloud induced by an external electric field. In the case of nanoparticles composed of noble metals such as gold, silver, or copper, the resonance is located in the visible or near UV range. The polarisability of a nanoparticle is directly proportional to four key parameters: its volume, its composition, its shape and its surrounding environment. It is these properties that make LSPR useful for sensor applications. In the case of isotropic particles, such as spheres, the LSPR spectrum shows only one absorption peak. In the case of an anisotropic particle, such as an ellipsoid, the absorption spectrum has two or more distinct peaks. If the absorption cross-section is measured with unpolarised light, multiple maxima are obtained. The key point for these type of systems is the possibility to decouple the resonances using polarised light. In this description the anisotropic system is considered microscopic, i.e. it is only made of one or two particles. In the case of a macroscopic sample, such as a colloidal solution of ellipsoids or nanorods, the absorption spectrum will always have multiple absorption maxima, and they cannot be decoupled because the sample is not globally anisotropic.On the other hand, if the sample has a global anisotropy such as aligned nanorods, or nanosphere organised in lines, it is possible to have a plasmon spectrum dependent on the light polarisation. Being able to decouple the resonances of an anisotropic sample makes it possible to measure a differential spectrum by taking the difference of the two absorption spectra. This is experimentally possible by using anisotropic transmission spectroscopy which measures the optical anisotropy. The advantage is to obtain a relative and differential spectrum more stable and reproducible. Moreover, it is now possible to follow the evolution of the optical response of the plasmonic particles no longer by measuring a spectral shift but by measuring the change in intensity of the signal at a fixed wavelength. This method is used on two case studies which are the measurement of the interaction of dihydrogen with gold nanoparticles, as well as the detection of low partial pressure of dihydrogen in a carrier gas (argon, and air) using palladium nanoparticles, for hydrogen sensing applications
Kaya, Zeynep. « Controlled and localized synthesis of molecularly imprinted polymers for chemical sensors ». Thesis, Compiègne, 2015. http://www.theses.fr/2015COMP2220.
Texte intégralMolecularly imprinted polymers (MIPs), also referred to as plastic antibodies, are synthetic biomimetic receptors that are able to bind target molecules with similar affinity and specificity as natural receptors such as enzymes or antibodies. Indeed, MIPs are used as synthetic recognition elements in biosensors and biochips for the detection of small analytes and proteins. The molecular imprinting technique is based on the formation of specific recognition cavities in polymer matrices by a templating process at the molecular level. For sensor and biochip development, fast binding kinetics of the MIP for a rapid sensor response, the integration of the polymers with transducers, and a high sensitivity of detection are among the main challenges. In this thesis, the above issues are addressed by developing MIP/gold nanocomposites by grafting MIPs on surfaces, using dedicated techniques like atom transfer radical polymerization (ATRP) which is a versatile controlled radical polymerization (CRP) technique. Theses ophisticated CRP techniques, are able to greatly improve the polymeric materials. The use of ATRP in the MIP field has been limited so far due to its inherent incompatibility with acidic monomers like methacrylic acid (MAA), which is by far the most widely used functional monomer. Herein, a new method is described for the MIP synthesis through photo-initiated ATRP using fac-[Ir(ppy)3] as ATRP catalyst. The synthesis is possible at room temperature and is compatible with acidic monomers. This study considerably widens the range of functional monomers and thus molecular templates that can be used when MIPs are synthesized by ATRP. The proposed method was used for fabrication of hierarchically organised nanocomposites based on MIPs and nanostructured metal surfaces containing nanoholes or nanoislands, exhibiting plasmonic effects for signal amplification. The fabrication of nanometer scale MIP coatings localized on gold surface was demonstrated. Optical transduction methods, namely Localized Surface Plasmon Resonance (LSPR) and Surface Enhanced Raman Spectroscopy (SERS) were exploited and shown that they hold great promise for enhancing the limit of detection in sensing of biologically relevant analytes including proteins and the drug propranolol

Um dispositivo eletrônico para teste laboratorial remoto ou point-of-care testing (POCT) foi desenvolvido para detecção de glicose, sendo três as suas unidades estruturais: a fonte de luz, o sensor plasmônico e o transdutor de sinal. Após testes na primeira unidade estrutural do instrumento, optou-se por fonte de luz do tipo laser de ondas contínuas, trabalhando no comprimento de onda 780 nm. A segunda unidade estrutural é resultante de técnicas de engenharia molecular e síntese coloidal de um sensor plasmônico, estável, consumível em única dose. Funcionalizou-se a superfície dos nanobastões de ouro (NBAu), revestindo-os com polieletrólitos e em seguida conjugou-se com enzima glicose oxidase (GO) em camadas, pelo método layer-by-layer (LBL). As camadas foram caracterizadas por espectroscopia UVVis- NIR e obteve-se uma relação qualitativa entre estas e seus respectivos espectros de ressonância localizada de plasmon de superfície (LSPR). A LSPR possibilita uma ampla variedade de aplicações em dispositivos sensores baseados neste fenômeno. Os NBAu sintetizados neste trabalho apresentaram dois modos de absorção: (i) 550 nm o qual corresponde ao modo de oscilação transversal e (ii) 744 nm para o modo de oscilação longitudinal e sua morfologia foi obtida por microscopia eletrônica de transmissão (MET). Foi possível investigar a estabilidade de nanobastões funcionalizados com concentrações de poliestirenosulfonato de sódio (PSS). O sensor plasmônico NBAu-PSS-Poliacrilamida(PAM)- GO distinguiu absorções para soluções de concentrações distintas de glicose. Para a terceira unidade estrutural do instrumento foram selecionados transdutores de sinal e desenvolveu-se uma abordagem experimental que permitiu defini-los e programá-los a fim de reproduzir respostas correspondentes àquelas de analisadores convencionais. Um analisador de modulações LSPR foi programado no dispositivo eletrônico e ocorreu em conjunto com a síntese das nanoestruturas. A especificação do emissor de luz, a construção do sensor NBAu- PSS-PAM-GO e a definição do transdutor de sinal, permitiram elaborar uma instrumentação prática para a diagnóstico rápido. Este trabalho veio reforçar a importância da aplicação de nanoestruturas anisotrópicas para reconhecimento de macromoléculas. Uma estratégia semelhante foi contemplada neste mesmo dispositivo eletrônico, demonstrada em anticorpos conjugados aos nanobastões para reconhecimento da proteína troponina, como prova de conceito.

Texte intégralWireless sensor networks (WSNs) play an important role in applications such as environmental monitoring, source tracking, and health care,... In WSN, sensors have the ability to perform data sampling, distributed computing and information fusion. To perform such complex tasks, clock synchronization and localization are two fundamental and essential algorithms. WSNs have been widely studied in the past years, and the scientific literature reports many outcomes that make them applicable for some applications. For some others, research still needs to find solutions to some of the challenges posed by battery limitation, dynamicity, and low computing clock rate. With the aim of contributing to the research on WSN, this thesis proposes new algorithms for both clock synchronization and localization. For clock synchronization, sensors converge their local physical clock to perform data fusion. By applying the clock synchronization algorithm, sensors converge the time difference and therefore work at the same rate. In view of dynamicity, low computing and sparsity of WSN, a new pulse-coupled decentralized synchronization algorithm is proposed to improve the precision of the synchronization. The benefit of this kind of algorithm is that sensors only exchange zero-bit pulse instead of packets, so not only the communication is efficient but also robust to any failure of the sensors in the network. Localization of sensors has been widely studied. However, the quality and the accuracy of the localization still have a large room to improve. This thesis apply Leave-out Sign-dominant Correlated Regions (LSCR) algorithm to localization problem. With LSCR, one evaluates the accurate estimates of confidence regions with prescribed confidence levels, which provide not only the location but also the confidence of the estimation. In this thesis, several localization approaches are implemented and compared. The simulation result shows under mild assumptions, LSCR obtains competitive results compared to other methods
