Selenium Dioxide Nanoparticles from Hibiscus Sabdariffa Flower Extract Induce Apoptosis in Bacterium (Gram-negative, Gram-positive) and Fungi

What is it about?

Hibiscus sabdariffa flower extract is used to make environmentally friendly SeO2 nanoparticles. UV-Vis spectra clearly exhibited a plasmon resonance band at 285 nm. FETEM analysis was used to analyze the morphology of SeO2 NPs, The results revealed that the particles dispersed and formed homogenous SeO2 NPs with the spherical shape, and the mean diameters of particles are 3 and 20 nm. The XRD pattern is used to confirm the crystallinity of nanoparticles. The presence of the peaks of Se-O is confirmed by FTIR. The nanoparticles also had antibacterial and antifungal (candida) efficacy against (gram-positive) bacteria. The biosynthesized of SeO2 NPs have the potential application to use in various physical applications, as well as in biomedicine.
