Beschreibungen/Notizen

• •Ag/GO was successfully synthesized by co-precipitation.•LAA was used as a reducing agent, which is easy to find, and eco-friendly.•AgNPs with size 17.65 ± 4.76 nm were decorated on GO.•Concentration and contact time significantly affect the antibacterial activity.•The antibacterial activity of Ag/GO increased when pH value was decreased. Herein, silver/graphene oxide (Ag/GO) nanocomposite was fabricated by co-precipitation with green reducing agent and then was characterized with modern analytical techniques. The antibacterial activities were conducted via the effects of Ag/GO concentration, time, and pH. Results show that silver nanoparticles were uniformly distributed on the GO sheets nanosized of 17.65 ± 4.76 nm. The antibacterial performance was optimized at pH 5.6, eradicating P. aeruginosa in 180 min at 50 µg/mL Ag/GO concentration and S. aureus in 480 min at 300 µg/mL Ag/GO. This demonstrates the potential of Ag/GO as an antibacterial nanocomposite material.
