Abstract

Due to its sustainable, economical, and environmentally benign methods, the green synthesis of nanoparticles has drawn a lot of attention. Given their distinct physicochemical characteristics and extensive range of uses, silica nanoparticles (SiO2) are one of the most widely used nanomaterials. This study highlights the variations in stability and antibacterial activity between silica nanoparticles synthesized chemically and green. Plant extracts were used in green synthesis, where phytochemicals served as capping and reducing agents to improve the stability of the nanoparticles. X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FTIR) were used to assess both chemically produced and green nanoparticles. The produced nanoparticles' antibacterial activity was assessed against three bacterial pathogens, comprising one Gram-negative strain and two Gram-positive strains. According to the findings, silica nanoparticles of both kinds showed strong antibacterial activity, but the green-synthesized nanoparticles were more stable because of the bioactive ingredients. This study highlights the promise of green synthesis as an efficient and sustainable process for synthesis of silica nanoparticles with exciting potential uses in biomedicine.
