摘要

Current, common methods to synthesize selenium nanoparticles use approaches which employ chemical methods. The weakness of these procedures, mainly extreme reaction conditions, production of toxic byproducts, and need of purification, highlights the necessity of alternative approaches. Here, we successfully synthesized biogenic selenium nanoparticles using different bacteria strains through an eco-friendly and green approach. Selenium nanoparticles with small and uniformly shape were synthesized with a r elatively homogeneous size distribution. Decay in bacterial growth was achieved against both Gram positive and Gram negative bacteria, without significant cytotoxicity effect towards human dermal fibroblasts (HDF) cells.
