摘　　要：硒,一种生物体不可缺少的微量元素,具有防治癌症、预防循环系统疾病等重要作用,当人体缺硒或过量摄入时,都会产生危害。在硒元素的各种存在形态中,纳米硒生物活性高、毒性低、易被生物体较好的吸收利用,是目前人体补充硒元素的可靠硒源。生物合成法是一种绿色、安全的合成方法,其中微生物法合成的纳米硒,具有耐高温、结构稳定、粒径小、颗粒大小均匀等优点,市场开发应用前景广阔。本文主要阐述了纳米硒的特征、合成方法、微生物合成种类、植物法合成,以及在市场初步应用,为生物合成纳米硒的理论研究基础提供参考。Selenium, an indispensable trace element for organisms, plays an important role in preventing cancer and circulatory system diseases. It will be harmful when the human body is short of selenium or excessive intake. Among various existing forms of selenium, nano-selenium has high biological activity, low toxicity and is easy to be absorbed and utilized by organisms. It is a reliable selenium source for human body to supplement selenium at present. Biosynthesis is a green and safe synthesis method. Nano-selenium synthesized by microbial method has the advantages of high temperature resistance, stable structure, small particle size and uniform particle size. It has a broad market development and application prospect. This paper mainly expounds the characteristics, synthesis methods, microbial synthesis types, plant synthesis and preliminary application in the market of nano-selenium, so as to provide reference for the theoretical research basis of biosynthesis of nano-selenium.
