A novel sensor based on electrochemical polymerization of diglycolic acid for determination of acetaminophen.

Diglycolic acid (DA) polymer was coated on glassy carbon (GC) electrode by cyclic voltammetry (CV) technique for the first time. The electrochemical performances of the modified electrode were investigated by CV and electrochemical impedance (EIS). The obtained electrode showed an excellent electrocatalytic activity for the oxidation of acetaminophen (ACOP).

[Electrochemical sensor for acetaminophen based on layer-by-layer self assembly technique].

A novel type of carbon nanotube-coated Au nanoparticle and [bmim]BF4 composite modified glassy carbon electrode was fabricated by a layer-by-layer self-assembly technique. The electrochemical performance of acetaminophen (ACOP) on the modified electrode was investigated by cyclic voltammetry. The Nafion/GNPs/RTIL/MWNTs/GC electrode showed an excellent electrocatalytic activity for the oxidation of ACOP and accelerated electron transfer between the electrode and ACOP.
