We have modified a glassy carbon electrode (GCE) with copper(I) oxide nanoparticles (NPs), nitrogen-doped graphene (N-graphene) and Nafion to obtain a novel sensing platform for the non-enzymatic detection of hydrogen peroxide. The deposition of the Cu2O NPs on N-graphene was accomplished by single-step chemical reduction. The nanocomposite was characterized by using X-ray diffraction and scanning...
We describe a molecularly imprinted electrochemical sensor for selective and sensitive determination of β2-agonists. It is making use of a combination of single-wall carbon nanotubes (SWNTs) with a molecularly imprinted sol–gel. The SWNTs were introduced in order to enhance electron transport and sensitivity. The imprinted sol–gel film with its specific binding sites acts as a selective recognition...
