Synthesis, Characterisation, and in Vitro Biocompatibility Studies of Selenium Nanoparticles Synthesized using Hybanthus Enneaspermus Plant Extract for Potential Biomedical Applications

Hybanthus enneaspermus (HE) is a traditional medicinal plant used for treating various disease conditions. Selenium nanoparticles (SeNPs) possess various properties such as anticancer, antioxidant, etc. The objective of the present study is to conduct green synthesis of selenium nanoparticles using Hybanthus enneaspermus(HE) and evaluate their biocompatibility. Leaves of HE are utilized for synthesizing SeNPs. Characterization studies of HE-SeNPs are carried out using UV spectrophotometry, FT-IR spectroscopy, and SEM. To check the biocompatibility, hemolytic assay, and Annexin V-PI assays are carried out. A change in color is observed after the addition of sodium selenite to the leaf extract. UV spectrophotometry gives a peak at 271 nm confirming the synthesis of SeNPs. FT-IR gives peaks at 3224, 1565, 1399, 1078, 784, and 717 cm-1 with a fingerprint of 3500 - 1000 cm-1. SEM analysis shows the spherical morphology of the SeNPs. HE-SeNPs at lower concentrations cause less hemolysis. However, HE-SeNPs are found to be less biocompatible, so further studies are needed to confirm their biocompatible nature. SeNPs synthesized from HE can be ideal for biomedical applications but further studies are required to check its biocompatibility.
