Abstract
Radiation is the emission energy or transition through space or through material medium in the form of a particle or wave. The radiation affects human body in highly complied processes. Various degrees of biological effects, from degrees to death of living tissues, involve a number of pathological change in human cells due to produce free radicals which are chemical species such as an atom, a molecule or an ion which contains unpaired electrons. In this study, gold nanoparticles (AuNPs) were synthesized by reducing agent gel and inhibition to reduce Au+3 ions of chlorooric acid (HAuCl4.3H2O) to nano gold. Requires reactive heating about 70°C. NPs were monitored by UV spectroscopy. The UV spectra showed 524 nm wavelength. The AuNPs, such as size, shape and stability, AFM and TEM techniques indicating a volume of 20-50 nm. Evaluation of antioxidant properties of AuNPs residues was done using DPPH assay. These nanoparticles have been found to be highly capable of antioxidants and can therefore be used as potential radical contaminants against harmful damage caused by free radicals.
