文题释义:
银纳米颗粒:
指由银原子组成的颗粒,其粒径通常在1-100 nm范围。大块的银材料表面具有抑菌性质早已为人熟知,其机制是位于材料表面的银原子可被环境中的氧气缓慢氧化,释放出游离银离子,这些银离子通过与细菌壁上巯基结合,阻断细菌的呼吸链,最终杀死附着在材料表面的细菌。
银离子的杀菌机制:抑制细菌细胞壁表面肽聚糖的合成,破坏细胞壁完整性,破坏细菌细胞膜;影响酶的活性,破坏蛋白质合成,干扰DNA、RNA合成;银纳米颗粒在被氧化过程中可产生活性氧自由基,可攻击生命大分子物质及细胞壁,使类脂中的不饱和脂肪酸发生过氧化,导致细胞膜结构破坏,并能够氧化蛋白质;银纳米颗粒的粒径大小是影响其抗菌性的重要因素。

 

摘要
背景:
目前大量研究证明银纳米颗粒具有良好的抗菌性能,现已得到广泛应用。
目的:从银纳米颗粒的抗菌机制、生物安全性及银纳米抗菌涂层进展等几个方面进行阐述,归纳国内外载银抗菌涂层的研究和发展方向。
方法:由第一作者检索1976年1月至2015年1月Web of Science数据库、Pubmed数据库、中国科技期刊数据库(中国知网)中的相关文献,检索关键词为“silver nanoparticles,titanium alloy,implant,antibacterial properties;biosecurity,coating;银纳米颗粒,钛合金,内植物,抗菌性,生物安全性,涂层”。
结果与结论:银纳米颗粒以其量子及小尺寸粒子效应,具备极大的比表面积,可很好地与病原微生物密切接触,发挥生物效应,具有优良的抗细菌、真菌、病毒及癌细胞等优点。但其诸多生物效应机制尚不明确,并且银纳米颗粒材料在体内的缓释作用时间、如何控制银离子的缓释仍未解决,长期动物实验也比较少。如何确保银纳米颗粒的长期应用对人体无不良反应,减少其毒性,仍需大量的实验室和临床研究。

Abstract:

BACKGROUND: Current numerous studies have confirmed that silver nanoparticles have been extensively applied due to their good anti-bacterial performances.

 
OBJECTIVE: To summarize the overseas and domestic research and development of anti-bacterial silver coating based on the anti-bacterial mechanism and bio-safety of silver nanoparticles as well as progression of anti-bacterial silver coating.
METHODS: The first author retrieved the databases of Web of Science, PubMed and CNKI for relative articles published from January 1976 to January 2015. The keywords were “silver nanoparticles, titanium alloy, implant, antibacterial properties, biosecurity, coating” in English and Chinese, respectively.

RESULTS AND CONCLUSION: Because of their small dimension and quantum effects, as well as great specific surface area, silver nanoparticles can be in close contact with pathogenic microorganisms to exert biological effects. Additionally, silver nanoparticles exhibit the excellent resistance to bacteria, fungi, viruses and cancer cells. However, most of their mechanisms of biological effects remain unclear, and there are unresolved problems about the slow-release time of silver nanoparticles in vivo and how to control the slow-release silver ions. Besides, there are fewer long-term animal experiments. Therefore, a large number of laboratory and clinical studies are needed to ensure that silver nanoparticles cannot cause adverse reactions during long-term administration and how to reduce their toxicity.
