what's the radical for linc oxide
Answers
Answer:
Zinc oxide nanoparticles (ZnO NPs) were confirmed in this work as good antioxidant source. They were biosynthesized by the preformed biomass of Aspergillus carneus when contacted with 1 mM zinc nitrate solution of pH 9 after 24 h at 150 rpm and 30°C. The biosynthesized NPs were moderately distributed, quasi-spherical in shape with clear edges and average size of 8-12 nm. The NPs retained full stability at 4°C for at least six months. Their zeta potential was found to be 18.3 mV. Crystalline nature of the ZnO NPs was suggested from diffraction rings appeared as lighted spots on the selected area electron diffraction (SAED) pattern and confirmed by the X-ray diffraction analysis. High radical scavenging activities (RSA) were found against peroxide (O22−) and 2,2–diphenyl-1-picrylhydrazyl (DPPH. Good activity was also recorded against hydroxyl (OH−) and superoxide (O2−) radicals.
