Abstract The increasing use of metal oxide nanoparticles demands a better understanding their health impact. Here, we report the synthesis copper (I) (Cu 2 O NPs) using cost‐effective chemical methods and assessed photocatalytic, antibacterial, anticancer properties. X‐ray diffraction (XRD) pattern verified its cubic structure. average crystallite size 11 nm was obtained Scherrer method. Fourier transform infrared (FTIR) spectroscopy confirmed formation Cu NPs. spherical morphology through field emission scanning electron microscopy (FESEM) analysis. High‐resolution transmission (HRTEM) estimated to be around 15 nm. photoelectron (XPS) spectra NPs showed peaks at 931.75 951.82 eV, corresponding 2p 3/2 1/2 , respectively. UV–vis revealed optical direct bandgap (2.33 eV) Under light irradiation, catalyst achieved tetracycline (TC) degradation efficiency 80% within 75 min. antibacterial properties against Klebsiella pneumoniae Bacillus subtilis agar disk diffusion have been investigated. also exhibited significant activity MCF‐7 cancer cells MTT assay, with an IC 50 value 18.88 µg/mL.

The growth of material science and technology places high importance on creating better processes for synthesizing copper nanoparticles. Thus, an easy, ecological, benign process producing nanoparticles (CuNPs) has been developed using Priestia sp. bacteria utilizing a variety low-cost agro-industrial wastes byproducts. biosynthesis CuNPs was conducted glucose medium ions salt solution, then it replaced by wastes. UV-visible spectroscopy, dynamic light scattering (DLS), X-ray diffraction (XRD), High-resolution transmission electron microscope (HR-TEM), Attenuated Total Reflectance Fourier transform infrared (ATR-FTIR), zeta potential were used to characterize the biosynthesized CuNPs. cytotoxicity Vero -CCL-81 cell lines, antibacterial antitumor properties human colon epithelial colorectal adenocarcinoma Caco-2-HTB-37 lines assessed. DLS studies revealed formation, with maximum concentration 6.19 ppm after 48 h, as indicated 0.58 Surface plasmon resonance (SPR) within 450 nm 57.73 particle size. 16S rRNA gene analysis that isolate is closely related megaterium deposited in NCBI GenBank accession number AMD 2024. various blackstrap sugar cane molasses being most effective reducing size 3.12 owing stabilizing active compounds. free contaminants, sphere-shaped structure assessment IC

Abstract Nanoparticle synthesis under environmentally friendly conditions has been conducted utilizing natural resources in order to reduce the reliance on hazardous chemicals. For example, utilization of microbial enabled production nanoparticles that exhibit biocompatibility, stability, and safety. Microorganisms facilitate growth crystals while preventing aggregation. They serve as both reducing agents capping by offering enzymes, peptides, poly(amino acids), polyhydroxyalkanoate, polysaccharides. In this review, we present an overview nanoparticle based microorganisms including bacteria, fungi, algae, actinobacteria, encompassing metals such gold (Au), silver (Ag), platinum (Pt), palladium (Pd), copper (Cu), titanium dioxide ((TiO 2 ), zinc oxide (ZnO), iron (Fe O 3 selenium (Se). The typically vary size from 1 100 nm various shapes spherical, rod-shaped, triangular, cubic, hexagonal shapes. Additionally, review discusses mechanisms behind metal microorganisms, whether they occur intracellularly or extracellularly.
