Optical fiber based hydrogen peroxide sensor

What is it about?

Green synthesis of nanoparticles and their applications in sensing area is of great interest to the research community. Herein we report a green approach for the synthesis of silver nanoparticles (Ag NPs) by using locust bean gum (LBG) polysaccharide and its application to detect hydrogen peroxide (H2O2). Ag NPs were synthesized by mixing optimized weight percent of LBG with a known quantity of silver nitrate (AgNO3) at 55–60 °C. Synthesized Ag NPs were characterized by UV–vis spectroscopy and a

Why is it important?

In this work, we have reported a simple, eco-friendly, one-pot synthetic route to prepare silver nanoparticles, by using LBG as a reducing and stabilizing agent. The Ag-NPs synthesized by this method were found to be stable over 7 months of period under study. The LBG stabilized Ag NPs were successfully employed in the fabrication of optical fiber based sensor for the detection of H2O2. The developed fiber optic sensor for the detection of H2O2 is simple, cost effective and portable and can be a
