Abstract

We herein report the antibacterial and sensing properties of dextrose reduced starch-capped silver nanoparticles (Ag-NPs). The synthesis involves the use of water, starch, and dextrose which are environmentally benign materials as the solvent, stabilizing, and reducing agent respectively while AgNO₃ was used as the silver precursor. The as-synthesised Ag-NPs were characterized using UV-vis absorption spectroscopy and high resolution transmission electron microscopy (HRTEM). Antibacterial study shows that the as-synthesised Ag-NPs show good antibacterial activities against E coli and P. aeruginosa while the sensitivity reaction showed that the as-synthesised Ag-NPs are very sensitive to H₂O₂, one of the reactive oxygen species (ROS) that possess a serious threat to biological system upto a concentration of 10^-10M.
