Researchers from the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences developed a novel approach of green synthesis of silver nanoparticles and reduced graphene oxide composite material (AgNPs@rGO) based on plasma technology.

This composite nanomaterial, according to the researchers, with much simplified , can be made into band-aids for wound sterilization and healing.

Abuse of antibiotics can cause bacterial resistance. Silver nanoparticles (Ag NPs) have excellent antibacterial properties and biocompatibility, and introduction of the two-dimensional material graphene can greatly improve dispersibility of the nanoparticles and improve the sterilization efficiency. However, the current preparation methods of AgNPs@rGO composite usually require such as using toxic and polluting chemical reagents.

In this research, the researchers employed high-voltage direct-current discharge plasma for fabrication of AgNPs@rGO by reducing both Ag+ ions and simultaneously.

"The advantage is obvious, and it's ready for application," said Prof. Huang Qing, who led the research team, "this electrical flash strategy for synthesis of AgNPs@rGO composite nanomaterial took only a very short period time (within one minute), which is different from traditional high-cost and time-consuming processing."

The as-fabricated AgNPs@rGO nanomaterial showed excellent disinfection effect and bio-compatibility, and could be used for wound healing band-aids, as demonstrated by the researchers.
