Abstract :

Fascinating green and cost-effective technique for the synthesis and preparation of silver nanoparticles for an easy assay for the detection of hydrogen peroxide as reactive oxygen species is described in the present study. Silver nanoparticles were capped using an extract of an algae harvested from the Arabian sea in Al-Fujairah, UAE. Nanoparticles were obtained in an optimum time of 3h under optimum temperature of 75Ã?Â?C in a water bath shaker. The optimum pH was found to be the normal pH of the plant extract (pH= 7). The nanoparticles were characterized by using Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), Dynamic Light Scattering (DLS) and Energy-Dispersive X-ray Spectroscopy (EDS). The nanoparticles were used for the sensing of hydrogen peroxide based on a colorimetric technique. The silver catalytic ability for the decomposition of hydrogen peroxide was assessed using different concentration of AgNPs, pH effect, temperature effect and different loads of hydrogen peroxide. The red color of the silver nanoparticles solution was found to change gradually to a transparent solution with the increase of the concentration of H2O2.
