Abstract

Voltammetric techniques have been introduced to monitor the formation of gold nanoparticles produced via the reaction of the amino acid glycyl-l-tyrosine with Au (III)(bromoaurate) in 0.05 M KOH conditions. The alkaline conditions facilitate amino acid binding to Au (III), inhibit the rate of reduction to Au (0), and provide an excellent supporting electrolyte for voltammetric studies. Data obtained revealed that a range of time- ...
