Cytotoxic and antifungal studies of biosynthesized zinc oxide nanoparticles using extract of Prosopis farcta fruit

Abstract

Zinc oxide nanoparticles (ZnO NPs) are one of the most widely used mineral particles. These nanoparticles are biocompatible and safe which can be used in medical-related industries. In this study, ZnO NPs were synthesized through an aqueous extract of Prosopis farcta fruit. Biosynthesized nanoparticles were identified through Ultraviolet-visible (UV-Vis), Powder X-Ray Diffraction (PXRD), Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersive X-ray analysis (EDX), and Transmission Electron Microscopy (TEM) methods. The results of electron imaging showed that biosynthesized nanoparticles are hexagonal in shape with range size between 40 and 50 nm. Electron spectroscopy results showed that the bandgap of biosynthesized nanoparticles is 3.9 eV. The results of antifungal assay against Candida albicans showed 32-64 and 128-512 µg/ml values for minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC), respectively. Cytotoxicity of nanoparticles against breast cancer cells (MCF7) was performed using WST-1 assay and its IC 50 was obtained 500 μg/ml.

Green Synthesis of Zinc Oxide Nanoparticles and Its Biomedical Applications: A Review

“…Emergence of new strains intended the researchers to improve this complex problem. ZnO-NPs are extensively explored as an antibacterial agent due to its unique properties like high surface area and its ability to induce oxidative stress [32] [33]. ZnO-NPs release Zn +2 ions which interact with the thiol functional group of respiratory enzymes.…”

Natural products and phytochemical nanoformulations targeting mitochondria in oncotherapy: an updated review on resveratrol

“…Nanotechnology is a multidisciplinary field that can be used in different fields such as engineering, medicine and chemistry [240][241][242]. Nanoparticles are structures with size less than 100 nm with capability of enhancing the bioavailability of drugs by encapsulating them and protection against degradation [8,243]. Also, they can reduce the clearance of drugs by escaping from phagocytosis system.…”

Biosynthesis, characterization and antimicrobial activities of zinc oxide nanoparticles from leaf & seed extracts of Malva neglecta Wallr.

“…[4] Zinc oxide nanoparticles (ZnO-NPs) are considered the most signi cant between the metal oxides NPs for their biocompatibility, high UV protection [5], low cost, non-toxicity, low electric resistance [6], thermal stability [7], and robustness [8]. So, these nanostructures are widely used in various elds such as the food industry [9], agriculture, solar cell [10], gas sensors [11], cosmetics [12], environmental remediation [13], and nally in medical elds such as gene delivery, wound healing [14], bio-imaging, drug delivery, biomedicine, especially in the elds of anticancer, antibacterial [15], anti-in ammatory, antioxidant, antifungal, and antidiabetic elds [16].…”
