Abstract
AbstractRecently, there has been a lot of interest in the fabrication of metal oxide nanoparticles (NPs) due to the growing importance of developing recyclable assets, affordable methods, sustainable substances, and safe compounds. The current study demonstrates the environmentally friendly fabrication of ZnO NPs through the use of an aqueous extract derived from discarded eggshells. The analysis of ZnO NPs involved the use of UV, x‐ray diffraction (XRD), Fourier‐transform infrared spectroscopy (FT‐IR), and field‐emission scanning electron microscopy (FE‐SEM) with EDX techniques. The anti‐germs effects of fabricated NPs on pathogens were investigated using the agar diffusion technique. The cell‐damaging effects were assessed using the MTT assay, whereas the photodecomposition capacity was examined with Congo red and methylene blue dye. X‐ray diffraction analysis revealed the existence of tetragonal crystal morphology. The generated ZnO NPs have a crystallite size of 17.6 nm. According to FE‐SEM examination, the created sample's average grain size has been determined to be between 20 and 30 nm. The sustainable production of ZnO NPs showed remarkable anti‐germs properties against human pathogenic organisms and had good efficacy in damaging Osteosarcoma cell lines (MG‐63) during the experiment. Additionally, it emerged that the manifestation of remarkable catalytic efficiency fell by 78.1% after 60 min for methylene blue. Based on the findings, it has been determined that sustainable production of ZnO NPs shows great potential across multiple fields such as anti‐germs, anti‐proliferative, and photodecomposition properties.
