Direct Enzymatic Glucose/O2 Biofuel Cell based on Poly-Thiophene Carboxylic Acid alongside Gold Nanostructures Substrates Derived through Bipolar Electrochemistry

Abstract: Bipolar electrochemistry (BPE) has been lately explored as a simple, reliable and novel electrochemical technique for the adjustment of various conductive substrates. Herein, BPE is performed to derive both of cathode and anode electrodes for the development of mediatorless/membraneless biofuel cell (BFC). On one hand, a preferable substrate for immobilization of bilirubin oxidase enzyme is prepared based on the electropolymerization of thiophene-3-carboxcylic acid (TCA) on an Au microfilm as a bipolar electro… Show more

“…After confirming the formation of the mediator deposition, the functional groups of GO/Co/chitosan were determined by FT-IR spectra to ensure the electrochemical properties of this complex modification ( Figure 2 b). According to previous reports on characteristic absorptions of chitosan, hydroxyl groups are usually shown in the range of 2800 to 2950 cm −1 with stretching vibration of around 3695 and 3073 cm −1 [ 17 ]. The FT-IR spectra of GO/Co/chitosan shown in Figure 2 revealed an absorption band of -OH group at 2876 cm −1 with stretching vibration from 3666 to 3023 cm −1 , respectively.…”

“…Thinner and smoother films were obtained by performing bipolar electropolymerization in an ionic liquid (Figure 1b). BE was also employed for the electrodeposition of thiophene‐3‐carboxylic acid on an Au microfilm [30] . Such layers exhibit a higher stability and a better adhesion to the Au surface than the ones electrodeposited by classic electrochemical methods.…”

“…BE was also employed for the electrodeposition of thiophene-3-carboxylic acid on an Au microfilm. [30] Such layers exhibit a higher stability and a better adhesion to the Au surface than the ones electrodeposited by classic electrochemical methods. This can eventually be attributed to the direct coupling of the reduction of quinone and the oxidation of the monomer, which decreases the potential difference required to trigger the electropolymerization, leading to less overoxidized oligomers.…”
