A sensitive hydrogen peroxide optical sensor based on polysaccharide stabilized silver nanoparticles†
Abstract
The paper reports a rapid and single pot synthesis of polysaccharide stabilized silver nanoparticles (Ag NPs). The ability of Ag NPs to catalyze the reduction of hydrogen peroxide (H2O2) is successfully explored for the development of an optical fiber H2O2 sensor in the concentration range of 10−2 to 10−6 M.
