Manganese-doped ZnS quantum dots (ZnS:Mn(II) QDs) were synthesized and modified with L-cysteine (L-Cys) and 6-mercaptonicotinic acid (MNA). This prevents the aggregation of the QDs and makes them available for the interaction with Cu(II) ions via Cu(II)-S interaction. As a result, the fluorescence of the QDs is quenched by Cu(II) due to an electron transfer mechanism. The QDs display two emission...
Molecular imprinting as a versatile technology has gained popularity in various fields for diverse species; however, protein imprinting still remains challenging due to some inherent problems but is potentially rewarding work. Herein, we reported a facile strategy to imprint phycocyanin (PC), as a template, using quantum dots (QDs) co-capped by thioglycollic acid and glutathione directly as functional...
