摘要
纳米银是研究和应用最广泛的纳米材料之一.近年来,为避免纳米银合成过程中产生有毒副产物,研究者在纳米银的绿色合成方面进行了诸多研究.首先,综述了生物法绿色合成纳米银,重点介绍了微生物法、植物提取物法;接着,介绍了纳米银抗菌性的机理和影响因素;然后,总结了纳米银的抗菌应用;最后,指出植物各组织和微生物细胞中富含的各类天然化合物均可完成纳米银的绿色合成,不同生物源合成纳米银的潜力有待进一步发掘.纳米银尺寸和形状的可控化以及在使纳米银发挥抗菌作用的前提下减少迁移、减少副作用是下一步的研究重点,对未来发展提出了建议.
Abstract
Silver nanoparticles are one of the most widely studied and applied nanomaterials.In recent years,extensive researches have been conducted on green synthesis of silver nanoparticles to avoid toxic by-products in the synthesis process.Herein,the green biological synthesis methods,especially the microbial method and plant extract method,of silver nanoparticles were firstly reviewed.The mechanism and influencing factors of the nano-silver antibacterial performance were introduced,followed by summarization on their antimicrobial applications.Finally,it was pointed out that the green synthesis of silver nanoparticles could be achieved by all kinds of natural compounds rich in plant tissues and microbial cells,while the synthesis potential of silver nanoparticles from different biological sources needed to be further explored.The future development directions should be focused on the size and shape control of silver nanoparticles as well as the reduction of migration and side effects when silver nanoparticles exert their antibacterial effects.
