Nanoparticle Bragg reflectors: A smart analytical tool for biosensing
In this work, we present a novel optical biosensor based on periodically alternated layers of SiO2 and TiO2 nanoparticles grown by wet methods and working as a Bragg mirror in a label free format. The sensing principle relies on the change of the optical response generated by variations in the diele...
