Claim Text:
1. A multi-analyte sensor, comprising: a substrate having an upper surface; a semiconductor nanostructure having an outer surface and disposed on said upper surface of said substrate; first metal-oxide nanoparticles functionalizing said outer surface of said semiconductor nanostructure and enabling detection of a target analyte in the presence of light, said first metal-oxide nanoparticles having a first adsorption profile; and second metal nanoparticles functionalizing said outer surface of said semiconductor structure, said second metal nanoparticles having a second adsorption profile, wherein said target analyte preferentially adsorbs on said first metal-oxide nanoparticles, and an interfering analyte preferentially adsorbs on said second metal nanoparticles.
