Recently, a comprehensive review paper devoted to roles of nano-Se in livestock and fish nutrition has been published in the Nanoscale Research Letters. The authors described in great details an issue related to nano-Se production and its possible applications in animal industry and medicine. However, molecular mechanisms of nano-Se action were not described and the question of how nano-Se is converted into active selenoproteins is not resolved. It seems likely that the gut microbiota can convert nano-Se into selenite, HSe or Se-phosphate with the following synthesis of selenoproteins. This possibility needs to be further studied in detail, and advantages and disadvantages of nano-Se as a source of Se in animal/poultry/fish nutrition await critical evaluations.
最近，一篇专门论述纳米硒在畜禽和鱼类营养中作用的综合综述文章发表在了《纳米研究快报》上。作者详细描述了与纳米硒生产及其在畜牧业和医学中可能应用相关的一个问题。然而，未描述纳米硒作用的分子机制，且纳米硒如何转化为活性硒蛋白的问题也未得到解决。肠道微生物群似乎有可能将纳米硒转化为亚硒酸盐、硒氢或硒磷酸盐，随后合成硒蛋白。这种可能性需要进一步详细研究，纳米硒作为动物/家禽/鱼类营养中硒源的优缺点有待批判性评估。
