Fabrication of Thin Film from Conducting Polymer/Single Wall Carbon Nanotube Composites for the Detection of Uric Acid

Abstract

Poly(2-aminobenzylamine)/single wall carbon nanotube (P2ABA/SWNTS) thin films were fabricated for the detection of UA by using electrochemical surface plasmon resonance spectroscopy (EC-SPR) technique. The suspension of 0.01% wt of carboxylated SWNTSs was assembled on the polymer film because of the electrostatic and van der Waals interactions between the COOH and NH 2 . The P2ABA/SWNTS thin film formation on gold electrode was studied by EC-SPR technique. In this work, uric acid was detected by EC-SPR in PBS buffer comparing with the interference response with ascorbic acid. EC-SPR uric acid sensor using P2ABA/SWNTS thin film can be applied for the detection of uric acid in urine.

Polyanilines with Pendant Amino Groups as Electrochemically Active Copolymers at Neutral pH

“…Furthermore, its incorporation was not possible beyond a few voltammetric cycles, indicating that the electropolymerization of the 2‐ABA homopolymer does not proceed to a large extent . However, more recently, the polymerization of both 2‐ABA and 3‐aminobenzylamine (ABA) in acid solution has been reported to produce stable films that can then be employed for adrenaline and uric acid sensing. Also, 4‐aminobenzylamine has recently been shown to electropolymerize on graphene in LiClO 4 aqueous solution .…”
