Abstract

In the last years photonic crystals (PhC) have opened new possibilities for the realization of high sensitive biophotonic devices. PhC offer their ability to control light propagation, allowing for instance to confine the light very efficiently into ultra-small volume space regions (nanocavities) and enhancing light-matter interaction. Very recently, high-sensitive biosensors based on one-dimensional macroporous silicon PhC nanocavities have been realized [1]. Such devices exploit the high sensitivity of PhC optical response to variations in the ambient conditions, such as caused by the binding of a small amount of analytes to the nanostructured surface.
