摘要
纳米金属材料具有纳米晶强化效应、光吸收率大、较高的表面能和单磁畴性能等优点,因其在医药、化学催化、抗菌抑毒等方面发挥着越来越重要的作用而受到人们广泛关注。近年来,随着全球石化资源消耗与日俱增,环境污染加剧,基于可再生资源的生物基分子介导纳米材料的制备研究方兴未艾。生物基分子是指直接或间接来源于生物质的小分子或大分子物质,它们多数具有生物相容性好、低毒、可降解、来源广泛、价格低廉等优点。且由于生物基分子多数具有独特的理化性质,如具有生理活性的旋光性、酸碱两性、亲水亲油性以及易与金属离子络合等,其介导合成的纳米材料还兼具其独特功能性,比如消炎、抗癌、抗氧化、抗病毒以及降血糖血脂等,进一步拓宽了纳米金属材料的应用领域。文中对近年来基于生物基分子介导纳米金属材料的制备及应用进行全面综述,为开展相关研究提供参考。
Nano-metallic materials are playing an important role in the application of medicine,catalysis,antibacterial and anti-toxin due to their obvious advantages,including nanocrystalline strengthening effect,high photo-absorptivity,high surface energy and single magnetic region performance.In recent years,with the increasing consumption of global petrochemical resources and the aggravation of environmental pollution,nanomaterials based on bio-based molecules have aroused great concern.Bio-based molecules refer to small molecules and macromolecules directly or indirectly derived from biomass.They usually have good biocompatibility,low toxicity,degradability,wide source and low price.Besides,most bio-based molecules have unique physical,chemical properties and physiological activity,such as optical activity,acid/alkali amphoteric property,hydrophilic property and easy coordination with metal ions.Thus,the corresponding nano-materials based on bio-based molecules also have unique functions,such as anti-inflammatory,anti-cancer,anti-oxidation,antiviral fall blood sugar and blood fat etc.In this paper,we give a comprehensive overview of the preparation and application of nano-metallic materials based on bio-based molecules in recent years.
