Aproximació Interferométrica als dispositius de biosensing basats en tecnologies de guies d’ones bimodals

O, ¿Que hi fa un alumne de primer de batxillerat en un centre de recerca de nanotecnologia?

or, What does a first year high school student do in a nanotechnology research center?


This research project was mainly done at the ICN2, under the supervision of the doctoral student Daniel Grajales. The stay at the research centre was done at the Nanobiosensors and Bioanalytical Applications group, driven by Professor Laura M. Lechuga, renowned all over the world for her work with different kinds of biosensors. Due to the particularity of the stay, the project is built around two different axes, which are on one hand the stay itself and the sensations and feelings involved on it, while on the other hand it can be found an interferometric approach to bimodal waveguide based optical biosensors. About the mentioned duality, it is showed on the work as a body which shows the learning process and its experimental culmination occurred at the ICN2, while the stay peculiarities are reflected at the introduction and conclusions. Since the learning process needed to conduct the experiment is long and complex, we can mainly talk of a theoretical research project with a concluding experiment.

About the theoretical content of the project, it can be said that it is an integral approach to optical biosensors based on bimodal waveguides’ technology. This kind of devices are intended to sense more than one analyte by taking profit of surface phenomena produced at the top of the waveguides (which due to their geometry are able to guide two different propagation modes).
