【摘要】：纳米金(AuNPs)凭借其独特的物理化学性质在多个领域得到了广泛的应用。相比于传统的化学、物理合成方法,微生物合成AuNPs凭借其环境友好、条件温和、绿色低毒等优势成为纳米技术领域的研究热点。相较于其他微生物,真菌能够分泌大量胞内或胞外蛋白/酶以及生物小分子,能够耐受较高浓度的AuCl_4~-,并且合成AuNPs的速度快、产量高、尺寸较为均一,因此具有大规模生产AuNPs的潜力。文章主要从合成AuNPs的真菌资源、影响纳米粒子形态的因素、合成机制与应用等方面进行综述,提出利用人工真菌群落合成AuNPs的新概念,并对未来该研究方向进行展望。
[Abstract]:Compared with traditional chemical and physical synthesis methods, AuNPs synthesized by microorganism has been widely used in many fields because of its unique physical and chemical properties. Compared with other microbes, fungi can secrete a large number of intracellular or extracellular proteins / enzymes and biological small molecules, and can tolerate higher concentration of AuClStud 4-, and the rate of synthesis of AuNPs is faster than that of other microbes, such as green, low toxicity and so on, and the fungi can secrete a large number of intracellular or extracellular proteins / enzymes and biological small molecules. Because of its high yield and uniform size, it has the potential to produce AuNPs on a large scale. This paper reviews the fungal resources for synthesizing AuNPs, the factors affecting the morphology of nanoparticles, the synthesis mechanism and application, etc. A new concept of synthesizing AuNPs from artificial fungal communities was proposed, and the future research direction was prospected.
