In this paper, mesoporous graphite-like carbon nitride (mpg-C3N4) combined with gold nanoparticles (Au NPs) was conducted to construct a luminol-hydrogen peroxide (H2O2) based electrochemiluminescent (ECL) immunosensor for prostate specific antigen (PSA) detection. The mpg-C3N4 exhibited large specific surface area and high porosity was synthesized from a simple precursor, which possessed abundant...
High-density and cross-linked copper-based metal-organic framework (Cu-MOF) sheets were successfully prepared via a simple oriented growth method on a carboxylated graphene-modified electrode surface. Hydrogen peroxide (H2O2) was selected as a model molecule to examine the performance of the thin film of Cu-MOF/graphene. The proposed sensor showed an extended linear detection range from 2.00 × 10−7...
In this work, a new enzymeless sensor for hydrogen peroxide (H2O2) was constructed by supporting CoFe nanoparticles on the nitrogen-doped graphene (CoFe/NGR). In this preparation, the graphene oxide (GO) is first used as substrate for the growth of CoFe layered double hydroxides (CoFe LDHs) through hydrothermal reaction. Then, the pyrolysis of CoFe LDHs/GO under NH3 produces CoFe/NGR. By supporting...
