dc.descriptionNovel silver nanoparticles (AgNPs) were synthesized using biomass from Eragrostis plana Nees, commonly known as Tough lovegrass, an invasive grass species in the Brazilian Pampa. AgNPs were synthesized in a one-step synthesis using the extract as a reducing agent for Ag+ ions and stabilizing agent. The results showed that the colloidal solution of AgNPs had a surface plasmon resonance (SPR) band at 410 nm. Through vibrational analysis, they showed that the OH, NH, CONH2, COC, COOH, and CO present in the extract were associated with reducing Ag+ ions. The synthesized nanoparticles were crystalline and, through morphological analysis, showed that the AgNPs produced had different shapes, with an average diameter of 23 ± 8 nm. The biosynthesized AgNPs exhibited high catalytic activity for reducing Toluidine blue (TB). The total reduction of TB with AgNPs in the presence of NaBH4 at 25 °C occurred after only 5 min of reaction.
