Resumo:
Research involving green synthesis for the formation of metallic nanoparticles has been standing out in the nanotechnology area for follow a different route from the conventional one whose substances used become responsible for presenting potential risks to the environment and biological systems. Thus, procedures that use compounds phytochemicals are shown to be efficient alternatives for the formation of metallic nanoparticles through the use of plant extracts. The Acai, typical of the Amazon region, has substances that have potential in the mediation of formation of nanoparticulate systems. The summaries of silver nanoparticles (AgNPs) were performed under three distinct conditions extract concentration, with procedures at room temperature and evaluating reaction speed, stability of Formed AgNPs and extract concentration. Nanoparticles produced in room temperature were subjected to antimicrobial tests, showing efficient results against the species Staphylococcus aureus, proving its microbiocidal effect especially against gram-positive bacteria.
