文摘

A new QDs by with high fluorescence intensity was successfully synthesized via embedding glutathione capped CdTe/ZnS QDs into cationic starch biopolymer. Fluorescence intensity of the QDs was obviously quenched after interacted with rifampicin. The fluorescence quenching was well described by the typical Stern–Volmer equation.
