200 p, 10.4 MB Bimodal waveguide interferometer device based on silicon photonics technology for label-free and high sensitive biosensing / González Guerrero, Ana Belén ; Lechuga, Laura M., dir. ; Pascual i Gainza, Jordi tutor (Universitat Autònoma de Barcelona. Departament de Física) ; Universitat Autònoma de Barcelona. Departament de Física
Els dispositius òptics biosensors basats en la detecció d'ona evanescent podrien superar les limitacions dels tests de diagnòstic actuals (que són lents i cars) degut a la possibilitat de realitzar les deteccions a temps reals i fent servir un esquema sense la necessitat de marcatges. [...]
Optical biosensor devices based on evanescent wave detection could overcome the limitations of conventional diagnostic tests (expensive and time-consuming) due to the possibility of carrying out the detection in real-time and using a label-free scheme. [...]
