The biosynthesis of algal-based zinc oxide (ZnO) nanoparticles has shown several advantages over traditional physico-chemical methods, such as lower cost, less toxicity, and greater sustainability. Tel +420-5-4513-3350. Zinc oxide nanoparticles (ZnO-NPs) have piqued the curiosity of researchers all over the world due to their extensive biological activity. 1 Introduction. Here, ZnO-NPs were synthesized using Cassia siamea (L. Redox Reaction is a chemical reaction in which oxidation and reduction occurs simultaneously and the substance which gains electrons is termed as oxidizing agent. In this paper, porous zinc oxide (ZnO) nanosheets were successfully prepared by a simple low-temperature hydrothermal method. The ZnO precursor was spin-coated on ITO glass at 2500 rpm for 30 s at the dry ambient atmosphere, followed by annealing at 320 °C for 12 min. The present work reports on the antiviral activity of coatings containing ZnO particles obtained by two simple synthesis routes using Aloe. Such unique properties are beneficial for achieving UV lasing at room. Various methods of synthesis have been adopted in the production of ZnO NPs so as to meet its high demand. dosage, form, labeller, route of administration, and marketing period. The samples have been characterized by employing X-ray diffraction method, and further analyzed using the Rietveld Refinement method.
