Findings on Nanoparticles Reported by Investigators at Nanjing Agricultural University (Graphene-Based Nanocomposite As an Effective, Multifunctional, and Recyclable Antibacterial Agent)

By a News Reporter-Staff News Editor at Life Science Weekly -- New research on Nanoparticles is the subject of a report. According to news reporting from Jiangsu, People's Republic of China, by NewsRx journalists, research stated, "The development of new antibacterial agents that are highly effective are of great interest. Herein, we present a recyclable and synergistic nanocomposite by growing both iron oxide nanoparticles (IONPs) and silver nanoparticles (AgNPs) on the surface of graphene oxide (GO), obtaining GO-IONP-Ag nano composite as a novel multifunctional antibacterial material."

The news correspondents obtained a quote from the research from Nanjing Agricultural University, "Compared with AgNPs, which have been widely used as antibacterial agents, our GO-IONP-Ag shows much higher antibacterial efficiency toward both Gram-negative bacteria Escherichia coli (E. coli) and Gram-positive bacteria Staphylococcus aureus (S. aureus). Taking the advantage of its strong near-infrared (NIR) absorbance, photothermal treatment is also conducted with GO-IONP-Ag, achieving a remarkable synergistic antibacterial effect to inhibit S. aureus at a rather low concentration of this agent. Moreover, with magnetic IONPs existing in the composite, we can easily recycle GO-IONP-Ag by magnetic separation, allowing its repeated use."

According to the news reporters, the research concluded: "Given the above advantages as well as its easy preparation and cheap cost, GO-IONP-Ag developed in this work may find potential applications as a useful antibacterial agent in the areas of healthcare and environmental engineering."
