生物法制备纳米硒的研究进展和应用前景

硒是人体必需的微量元素之一,对人类生存发展至关重要。作为一种新兴的生物纳米技术,研究制备纳米硒的方法越来越受到人们的重视,有着广阔的应用前景。本研究归纳了3种制备纳米硒的方法,即物理法、化学法和生物法。并详细介绍了生物法合成纳米硒,这种合成方法反应条件更温和、反应更迅速、绿色无污染且可持续发展,是制备纳米硒的3种方法中最优良的合成方式。本研究归纳了国内外近5年常见的表征纳米硒方法,如透射电子显微镜、傅里叶红外光谱、X射线衍射和紫外可见吸收光谱,并就目前的研究进展,对硒产业的应用方向进行归纳,即植物补硒、动物补硒和药物开发,希望给其他学者探索研究制备纳米硒提供新思路,并对探索纳米硒的应用研究进行展望。

Nano-selenium Prepared by Biological Method: Research Progress and Application Prospect

Selenium is one of the trace elements required by human body, and it is very important for the survival and development of human beings. As a new type of bio-nanotechnology, the method of researching and preparing nano-selenium has attracted more and more attention and has broad application prospects. This article summarizes three methods of preparing nano-selenium, which are physical method, chemical method and biological method. It also introduces the synthesis of nano-selenium by biological method. This synthesis method has mild reaction conditions and fast reaction, and is pollution-free and sustainable, which is the best synthesis method among the three. This article also summarizes the common methods for characterizing nano-selenium in the past five years at home and abroad, such as transmission electron microscopy, Fourier infrared spectroscopy, X-ray diffraction and ultraviolet-visible absorption spectroscopy, and discusses the application direction of the selenium industry such as plant selenium supplementation, animal selenium supplementation and drug development, aiming to provide new ideas for the preparation of nano-selenium, and to explore the application prospects of nano-selenium.
