Abstract
Semiconductor materials having a porous texture are modified with a recognition element and produce a photoluminescent response on exposure to electromagnetic radiation. The recognition elements, which can be selected from biomolecular, organic and inorganic moieties, interact with a target analyte to produce a modulated photoluminescent response, as compared with that of semiconductor materials modified with a recognition element only.
