Comparison of Antioxidant and Antimicrobial Properties of Zinc Oxide and Selenium Oxide Nanoparticles Using Verbascum Kotschyi Boiss. & Hohen

Abstract

Nanoparticle applications have been studied in many fields in recent years. Among these studies, the synthesis of nature-friendly and healthfriendly nanoparticles through green synthesis attracts much attention. These investigations also highlight the significance of several plant species, many of whose worth and traits remain unknown. The goal of this work is to create zinc oxide and selenium nanoparticles from Verbascum kotschyi Boiss. & Hohen., a plant species that hasn't received much attention, and to ascertain the antioxidant and antibacterial qualities of these nanoparticles. To accomplish this, three distinct techniques (DPPH, CUPRAC, and FRAP) were used to assess the produced nanoparticles' in vitro antioxidant capabilities after SEM, EDX, and FTIR analyses. Furthermore, the disk diffusion technique was utilized to ascertain the antibacterial efficacy of these nanoparticles against both gram-positive and gram-negative bacteria and fungus. In conclusion, V. kotschyi-derived zinc oxide nanoparticles outperformed selenium nanoparticles in terms of antibacterial activity. But when it came to antioxidant activity, selenium nanoparticles outperformed zinc oxide nanoparticles. Thus, it was determined that the products created by nanoparticle synthesis from Verbascum kotschyi have properties that can be used in different fields.
