Abstract

Photoluminescence (PL) enhancements of CdTe nanoparticles (NPs) and nanowires (NWs) are observed with the bioconjugation of metal NPs using d-biotin and streptavidin in solution. In the presence of metallic nanoparticles, strong enhancement of excitonic light emission of nanoparticles is observed. The enhancement effect is explained in terms of plasmon-assisted absorption of incident light and plasmon-induced increase of nanoparticles dipole moments. This supermolecules and bioconjugates system can be useful to build further efficient photonic devices and biological sensors.
