Journal ArticleDOI
A graphene oxide-based electrochemical sensor for sensitive determination of 4-nitrophenol.
TL;DR: This electrochemical sensor was further applied to determine 4-NP in real water samples, and it showed great promise for simple, sensitive, and quantitative detection of 4- NP.
Journal ArticleDOI
Green synthesis of silver nanoparticles–graphene oxide nanocomposite and its application in electrochemical sensing oftryptophan
TL;DR: The experimental results demonstrated that the nanocomposite possessed the specific features of both silver nanoparticles and graphene, and the intrinsic high specific area and the fast electron transfer rate ascribed to the nanohybrid structure could improve its electrocatalytic performance greatly.

TL;DR: In this paper, a nanohybrid composed of Ag@Cu2O heterogeneous nanocrystals supported on N-doped reduced graphene oxide (Ag@cu2O/N-RGO) has been synthesized by a simple wet-chemical method.
Journal ArticleDOI
Electrochemical determination of bisphenol A in plastic bottled drinking water and canned beverages using a molecularly imprinted chitosan–graphene composite film modified electrode
TL;DR: A novel electrochemical sensor based on an acetylene black paste electrode modified with molecularly imprinted chitosan-graphene composite film for sensitive and selective detection of bisphenol A (BPA) has been developed and successfully employed to detect BPA in plastic bottled drinking water and canned beverages.
Journal ArticleDOI
Electrochemical behavior and voltammetric determination of vanillin based on an acetylene black paste electrode modified with graphene-polyvinylpyrrolidone composite film.
TL;DR: The graphene-polyvinylpyrrolidone composite film modified acetylene black paste electrode (GR-PVP/ABPE) was fabricated and used to determine vanillin and under optimal experimental conditions, the oxidation peak current was proportional to vanillin concentration.
