2. ReflectÃmetro controlado por computador e sua aplicaÃÃo na detecÃÃo de hidrogÃnio com filmes finos de palÃdio e ouro/palÃdio
This work reports the development and implementation of a computer controlled optical reflectometer and use of the system for characterization of gold, palladium and gold-palladium thin films, with the latter two structures used as transducers for hydrogen detection. The system is designed with several parts actuated by stepper motors with an electronic inte

3. EletroquÃmica acoplada à ressonÃncia de plÃsmons de superfÃcie no estudo de adsorÃÃo de proteÃna em filme fino
Biosensor is a device in which the biological source material, such as enzyme, organelle, animal or vegetable tissue, microorganism, antigen or antibody, nucleic acids, lectina, among others is immobilized close to an adequate transducer. Therefore, the electrode/biomolecule/ solution interface characterization consists in one of the main stages for biosenso

4. PreparaÃÃo de materiais nonoestruturados para Ãptica nÃo linear
Foram desenvolvidos trÃs sistemas nanoestruturados contendo nanopartÃculas (NP) de prata cuja resposta Ãptica nÃo linear foi engrandecida devido à excitaÃÃo de plasmons superficiais nas NP. O primeiro material foi formado de NP de diÃxido de titÃnio (TiO2), NP de prata, e corante-laser rodamina 610 em matriz de PVA. Sabe-se que materiais contendo di

5. Sensor Ãptico em fibra multimodo baseado em ressonÃncia de plÃsmons de superfÃcie / Multimode optical fiber sensor based on surface plasmon resonance
This work is directed to the theoretical and experimental study of the surface plasmon resonance (SPR) effect in multimode optical fibers and its application in the development of fiber sensors. A review of the theoretical framework related to surface plasmon oscillations (SPO) is first presented, that includes the analysis of conditions for their existence

6. EspectrÃmetro de plÃsmons de superfÃcie no infravermelho para o desenvolvimento de biosensores
The development of sensors based on surface plasmon oscillations (SP) in metals is based on the high sensitivity of these oscillations to small fluctuations in the optical properties of the medium adjacent to the metallic surface. It is also possible through the characterization of these oscillations to determine optical properties and thicknesses of thin fi
