Abstract

Abstract Red elemental nano-selenium, which is an important biological form of selenium, exhibits very low toxicity and remarkable biological properties and thus has several positive effects. For instance, it shows antioxidation and antistress characteristics, promotes growth and improves immunity. However, owing to its nanoscale size, it is very difficult to disperse and stabilize during synthesis and storage. In this study, nanoscale selenium with a mass content of 2.06% and an average particle size of 49 nm was prepared by the chemical reduction method. The analysis demonstrated that the surface phospholipids formed lamellar structures after directional freezing, and the nano-selenium particles were distributed in the middle of the lamellar. The nano-selenium particles were efficiently dispersed due to their lamellar structure and amphiphilicity. The particles displayed excellent stability and remained relatively unchanged after 20 days of storage in solution or solid state. The difficulties associated with the dispersion and storage stability of nanometer selenium during preparation were solved.

磷脂包封纳米硒的合成及稳定性研究

红色单质纳米硒是硒的一种重要生物形态，具有极低的毒性和显著的生物学特性，具有多种积极作用。例如，它具有抗氧化和抗应激特性，促进生长和提高免疫力。然而，由于其纳米级的尺寸，在合成和储存过程中很难分散和稳定。本研究采用化学还原法制备了质量含量为2.06%、平均粒径为49 nm的纳米级硒。分析表明，表面磷脂在定向冷冻后形成片层结构，纳米硒颗粒分布在片层中间。纳米硒颗粒具有片层结构和两亲性，具有较好的分散效果。颗粒在溶液或固体状态下贮存20天后，表现出优异的稳定性，保持相对不变。解决了纳米硒在制备过程中存在的分散和贮存稳定性问题。

期刊介绍： Green Processing and Synthesis is a bimonthly, peer-reviewed journal that provides up-to-date research both on fundamental as well as applied aspects of innovative green process development and chemical synthesis, giving an appropriate share to industrial views. The contributions are cutting edge, high-impact, authoritative, and provide both pros and cons of potential technologies. Green Processing and Synthesis provides a platform for scientists and engineers, especially chemists and chemical engineers, but is also open for interdisciplinary research from other areas such as physics, materials science, or catalysis.
