Evaluation of Antimicrobial, Antioxidant, and Cytotoxicity Activities of CuO Nanopellets Synthesized by Surfactant-Free Hydrothermal Method

Abstract

Copper oxide nanopellets (CONPs) were produced by hydrothermal strategy. The particles were characterized by distinctive techniques. The synthesized particles were found to have pellet morphology with nonuniform thickness and varying sizes extending between 200 and 550 nm. Studies revealed their microbial nature against both Gram-positive and Gram-negative microscopic organisms, specifically Staphylococcus aureus, Bacillus subtilis, Pseudomonas fluorescens, and Escherichia coli and a plant parasitic pathogen Fusarium oxysporum. Studies demonstrated the antioxidant ability of CONPs at higher concentrations. In this paper, cytotoxicity was measured by blood hemolysis. Anticancer activity of CONPs tested against PC-3, HCT116, A549 and MDA-MB-231 cell lines after 24 hours exhibited IC50 values of 72.27, 144.2, 173.9, and 13.07 μg/mL, respectively. Although these phenomena have been determined in other reports, this report is indeed of significance for CONPs within the particle length of 200–550 nm.

Photocatalytic Activity Induced by Metal Nanoparticles Synthesized by Sustainable Approaches: A Comprehensive Review

“…Interestingly, recent literature do not present the complete picture of photocatalytic activity of metal NPs synthesized with the aid of plant extracts, and hence, this review paper tries to address the gaps, by providing insights into the development of novel NPs towards treatment of dye-contaminated wastewater with low price and high efficiency, via photocatalysis. employed for the preparation and stabilization of metallic NPs (Chen et al, 2001;Geethalakshmi and Sarada, 2012;Jamkhande et al, 2019, Krishna et al, 2016aPrashanth et al, 2016b;Krishna et al, 2017a;Krishna et al, 2017b;Sathyananda et al, 2021a).…”

An evaluation of noble nanocomposites based on zinc oxide: synthesis, characterization, environmental, optical and biomedical applications

“…ZO being a wide band gap semiconductor, it possesses a wide range of useful properties including electrical, chemical, optical and magnetic properties. Moreover, ZO can be applied in many evolving applications over gas sensing [12], catalysts [13], semiconductors [14], UV-shielding materials [15], nano generators [16], anticancer agents [17][18][19][20][21][22][23][24][25][26][27][28], antiviral and antibacterial agents [29][30][31]. Recent literatures revealed that undoped ZO and doped ZO find various interesting bioapplications .…”
