Abstract

A completely green and large scale controlled synthesis of stable, smaller sized (<5 nm) and monodispersed quasi spherical starch-capped silver nanoparticles (Ag NPs) using maltose as the reducing agent without any complexant or accelerator is presented. High concentration of the reducing saccharides produced via hydrolysis of maltose and partial hydrolysis of starch as the reaction time increases controls the particle diameter within the smaller size range.
