Research group in optics, photonics and biophotonics from Universidad Politénica de Madrid attended to the 9th Spanish Reunion in Optoelectronics in order to present experimental results obtained within the framework of the Project Enviguard among others and the support of several institutions.

“Sub-micrometric reflectometry for localized label-free biosensing” was presented by Dr. Rafael Casquel and promotes a novel and promising biosensing technique based on Reflectometry at a Profile Level (RPL).  It potentially allows detecting the precise allocation of biomolecules along the surface, their position and shape. This technique equals or improves Limit of Detection in relation to classical reflectometric biosensing methodologies, and could be used as an alternative interrogation system at WP4 from Enviguard Project.

“Resonant nano-pillars arrays as optical biosensors” poster presented by Phd student Ana López Hernández shows the motivation and characterization of this type of nanopillars based on Bragg Reflectors, as sensitive structures used for biochemical detection. According to the results it seems adequate to use them as biological sensors, in order to significantly increase sensitivity and detect presence of different species as toxins (WP4-Enviguard) among others.
