摘要

为了评估氧化锌纳米粒子（ZnO NPs）清除自由基和抑制细菌发展的效果，我们在氯化锌和氯化胆碱的深共晶混合溶剂（ZC-DES）中合成了氧化锌纳米粒子。通过傅立叶变换红外光谱测定，Zn-O 的振动模式和伸展模式分别为 619 cm-1 和 1607 cm-1。紫外可见光谱分析用于计算绿色合成纳米粒子的带隙值。XRD 衍射图显示了氧化锌纳米粒子的纳米晶体性质。在 1000 克/盘的条件下，氧化锌纳米粒子能有效限制大肠杆菌的生长，显示出 13 毫米的抑制区。在 1000 克/毫升的条件下，它们能清除 54.12% 的 DPPH 和 47.13% 的 DMPD 自由基。因此，由于其抗菌特性，合成的氧化锌纳米粒子可用于生物医学应用。

Green synthesis of ZnO nanoparticles in Zinc chloride:Choline chloride deep eutectic solvent-characterization antibacterial and antioxidant agents

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.
