Abstract
Mn-doped CdTe nanoparticles (NPs) were synthesized via a novel, facile method at low temperature. The doped NPs were directly synthesized in aqueous solution by mixing CdCl2·2.5H2O, fresh NaHTe solution, thioglycolic acid (TGA) and MnCl2·4H2O under suitable conditions. Mn-doped CdTe NPs evaluated as fluorescence sensors for bovine serum albumin (BSA) in aqueous solution. Experiment results showed that the fluorescence emission of Mn-doped CdTe NPs was enhanced significantly by BSA, while other substances exhibited no significant effect on NPs. Based on the distinct optical properties of Mn-doped CdTe NPs with BSA, Mn-doped CdTe NPs can be developed as potential identified fluorescence sensors for determination of brovine serum albumin (BSA) in aqueous solution.
