A Comparative Study on Amperometric Detection of Urea by Polyaniline and Poly (O-anisidine) Film under Galvanostatic Method| Chapter 6 | Current Topics on Chemistry and Biochemistry Vol. 5

 On an indium tin oxide (ITO) substrate, the development mechanism of polyaniline (PANI) and poly (O-anisidine) (POA) with the supporting electrolyte HClO4 has been investigated. Many scientists studied polyaniline, an ecologically stable polymer, by becoming interested in the redox characteristics associated with the chain of nitrogen atoms. In an aqueous solution with the supporting electrolyte HClO4 at a temperature of 270C, the PANI and POA polymer film was produced utilizing the electrochemical polymerization technique under galvanostatic conditions. The organized materials were characterized using analytical techniques including UV-visible, FTIR, and FE-SEM examinations in order to compare the amperometric response of PANI and POA film on aurease enzyme in conventional sensor. The effectiveness of the generated sensor was assessed, and the urea biosensor produced showed a quicker response time (3 s), a wider dynamic range (1 10-9 to 9 10-9 M), and a detection limit that was determined to be 1 10-9 M. For roughly 40 days, about 80% of the enzyme's activity is still present. With polyaniline, a customized sensor performs better than with poly (O-anisidine).
