Abstract：
In recent years, selenium nanoparticles (SeNPs) have attracted expanding consideration, particularly in the nanotechnology field. This element participates in important biological processes, such as antioxidant defense, immune function, and thyroid hormone regulation, protecting cells from oxidative damage. Selenium in the form of nanoscale particles has drawn attention for its biocompatibility, bioavailability, and low toxicity; thus, it has found several biomedical applications in diagnosis, treatment, and monitoring. Green methods for SeNP synthesis using plant extracts are considered to be single-step, inexpensive, and eco-friendly processes. Besides acting as natural reductants, compounds from plant extracts can also serve as natural capping agents, stabilizing the size of nanoparticles and contributing to the enhanced biological properties of SeNPs. This brief overview presents the recent developments in this area, focusing on the synthesis conditions and the characteristics of the obtained SeNPs.
摘要：
近年来,硒纳米颗粒(SeNPs)吸引了越来越多的考虑，特别是在纳米技术领域。这种元素参与重要的生物过程，比如抗氧化防御，免疫功能，和甲状腺激素调节，保护细胞免受氧化损伤。纳米颗粒形式的硒因其生物相容性而受到关注，生物利用度，低毒性；因此，它在诊断中发现了几种生物医学应用，治疗,和监测。使用植物提取物合成SeNP的绿色方法被认为是单步的，便宜,和环保工艺。除了作为天然还原剂，来自植物提取物的化合物也可以作为天然封端剂，稳定纳米颗粒的大小，并有助于增强SeNPs的生物学特性。这份简要概述介绍了这一领域的最新发展，重点介绍了合成条件和所得SeNPs的特性。
