Abstract

N-(2-hydroxybenzyl)-valine (VP) and N-(2-hydroxybenzyl)-isoleucine (ILP) organic ligands have been utilized as reducing and surface functionalizing agents in the synthesis of silver nanoparticles (AgNPs) with metal ion interacting functionality. VP and ILP metal interacting ligands functionalized AgNPs exhibited selective colorimetric sensing of toxic Cd²⁺, Hg ²⁺ and Pb²⁺ metal ions in aqueous solution at ppm level. The colorimetric sensitivity and metal ion selectivity of VP- and ILP-AgNPs were modulated by incorporating co-stabilizing agents. Importantly, ILP functionalized AgNPs selectively detected Cd²⁺ ions in the polluted ground water samples also.
