Mesoporous silicon photonic crystal microparticles: towards single-cell optical biosensors†
Abstract
In this paper we demonstrate the possibility of modifying porous silicon (PSi) particles with surface chemistry and recognition molecules (antibodies) such that these devices could potentially be used for single-cell identification or sensing. This is achieved by modifying PSi Rugate filters viahydrosilylation with surface chemistry that serves firstly, to protect the silicon surfaces from
