Abstract

Highly sensitive biosensing of concanavalin A (Con A) has been developed based on the attenuation of FRET efficiency between amine-terminated quantum dots and mannose-stabilized Au nanoparticles in the presence of Con A, which inhibits the H-bonding formation of the QDs-AuNPs assembly, thereby causing the fluorescence recovery.
