(Ch) in conjunction with microwave technology. Based on the morphological analysis, it was
determined that the Ch-St-SeNPs were spherical and had sizes that varied between 8.0 and
17.0 nm. In addition, the DPPH radical scavenging test was conducted to evaluate the
antioxidant effectiveness. The results showed that the green nanoparticle, prepared at 100.0
mg/mL, exhibited the highest scavenging capacity (297.1±10.2 mg g− 1). The concentrations …
