Ag nanoparticles modified Fe3O4/reduced graphene oxide and their acetone sensing properties

Exhaled acetone in the non-invasive diagnosis of type Ⅰ diabetes is one of the representative biomarkers. In this work, the Ag nanoparticles (NPs) modified Fe3O4/rGO composites was synthesized through a simple hydrothermal reaction, which could be a potential acetone sensor for painless and rapid breathing analysis. Through SEM and TEM, it was found that Ag nanoparticles were uniformly distributed on the surface of rGO sheets embedded in...
