Electrocatalytic effect of nano-wrinkled layer carbonaceous electrode: determination of folic acid by differential pulse voltammetry

Synergistic Electrochemical Amplification of Ferrocene Carboxylic Acid Nanoflowers and Cu Nanoparticles for Folic Acid Sensing

“…16,17 Electrochemical sensors for FA detection, as reported, are usually developed according to the principle that the C (9) -N (10) connecting pterin and p-aminobenzoic acid on FA molecular is oxidized to C (9) = N (10) with the loss of two electrons and two protons, as shown in Scheme 1. [18][19][20] To obtain an enhanced response signal, numerous electroactive materials are applied to improve the electrochemical properties of an electrode because of their large specific surface area, considerable active sites, fast electron transfer, and unique catalytic effect. For example, graphene, 21 nano-metal, 22,23 molecularly imprinted polymer (MIP), 24,25 and some composite materials 26,27 were widely used to modify an electrode in many FA sensors.…”
