Abstract
Blade coating method was employed to fabricate the pure graphene oxide sensors, whose sensitivity turned out to be about 10−9 M for detection of lead ions (Pb2+). To improve its ability to detect Pb2+ at much lower concentration, modification with 50–200 nm Au nanoparticles (AuNPs) was performed on...
