Abstract
To assess the effectiveness of zinc oxide nanoparticles (ZnO NPs) in scavenging free radicals and inhibiting the development of bacteria, they are synthesized in a deep eutectic solvent mixture of zinc chloride and choline chloride (ZC-DES). Zn–O exhibits vibrational and stretching modes at 619 cm−1 and 1607 cm−1, respectively, as determined by FTIR spectroscopy. The UV–Vis spectra analyses are used to calculate the band gap values for the green synthesized nanoparticle. The XRD diffractogram demonstrates the nanocrystalline nature of ZnO NPs. ZnO NPs effectively limit E. coli growth at 1000 g/disc, exhibiting a 13 mm zone of inhibition. They scavenge 54.12 % DPPH and 47.13 % DMPD free radicals at 1000 g/mL. Hence, the synthesized zinc oxide nanoparticles can be used for biomedical applications due to their antibacterial properties.
