Sensitive detection of Trifluralin in untreated human plasma samples using reduced graphene oxide modified by polyethylene imine and silver nanoparticles: A new platform on the analysis of pesticides and chemical injuries

Trifluralin is one of herbicide which is widely distributed in the human body after absorption, whose target organs can be adipose tissue, kidney, liver, adrenal gland, skin and blood. In this work, we successfully designed a new platform based on silver nanoparticles (Ag NPs) as signal amplifier and reduced graphene oxide modified by polyethylene imine (rGO-PEI) as polymeric substrate for sensitive detection and determination of Trifluralin in...
