dc.title.alternativeFunctionalized heterocyclic ligands 2 5 dimercapto 1 3 4 thiadiazole DMT 2 amino 5 mercapto 1 3 4 thiadiazole AMT 2 methyl 5 mercapto 1 34 thiadiazole MMT 3 amino 5 mercapto 1 2 4 triazole AMTr 2 mercapto 4 methyl 5 thiazoleacetic acid MMTA and folic acid FA chitosan Chi and bovine serum albumin BSA were used as capping agents for the synthesis of metal and semiconductor nanoparticles SC NPs They were characterized by UV visible fluorescence and FT IR spectral and XRD HRTEM zeta potential and dynamic light scattering techniques The DMT capped Au and Ag nanoparticles were used to determine Hg II with high selectivity and sensitivity MMTA CdS NPs and FA AuNPs were utilized to determine Cu II with high sensitivity The toxic food additives melamine and bisphenol A were determined using AMTr AuNPs and BSAAuNPs respectively Endosulfan and malathion pesticides were determined using AMTr AuNPs and Chi AgNPs respectively FA AuNPs were used to determine protamine and heparin drugs by spectrofluorimetry Further we have studied the selectivity of metal and SC NPs towards all the analytes
