Emergence of the selective ultra-sensing of Ag(I): Thiolactic acid as efficient capping agent for cadmium chalcogenide quantum dots in modulating photoluminescence and metal reception
Turn-off photoluminescence-based assay for selective and sensitive detection of Ag(I). Ultrasensitive LOD is found to be 50 nM/L and free from other metal interferences. Interesting role of TLA capping on PL and metal sensing selectivity of TLA-CdTe QDs. Pendent methyl of TLA effectively impedes secondary coordination of carboxyl oxygen.
