Single-step synthesis of AgNPs@rGO composite by e-beam from DC-plasma for wound-healing band-aids

Currently, there is a huge demand for medical biomaterials aimed to improve antibacterial effect and promote wound healing. In this work, a facile and single-step approach of synthesizing silver nanoparticles (AgNPs) and reduced graphene oxide (rGO) composite material (namely, AgNPs@rGO) using high-...
