Selective turn-on fluorescence assay of 6-thioguanine by using harmine-modified silver nanoparticles.


This article reports on a novel fluorescence resonance energy transfer (FRET) system between harmine and silver nanoparticles (AgNPs), in which harmine acts as the donor and AgNPs act as the acceptor. As a result of FRET, harmine fluorescence is quenched efficiently with a corresponding Stern-Volmer constant of 3.61 × 10(11)  L/mol. It was found that upon… (More)
