Polypyrrole, carboxylic acid derivative

Several groups have studied the synthesis of carboxylic acid derivatives of polypyrrole however, the electrochemistry of very few carboxylic acid substituted polypyrroles has been reported. Smith et al. [64] reported... 

A number of other conducting polymer derivatives have been used for immobilizing enzymes and redox mediators for biosensor applications. Among these polymers are poly (tyramine) [167] and poly(l-(5-aminonaphthylethanoic acid) [168], which have accessible amine and carboxyl functionalities, respectively, for covalently linking to complementary groups on available amino acid residues of enzymes. Polypyrrole and polythiophene derivatives have also been widely exploited for covalent immobilization of enzymes, which then function as the sensing layers in efficient biosensors [169,170].
