Abstract

Nanocomposite film comprising of polyaniline (PANI) and single walled carbon nanotubes (SWCNT) has been fabricated onto indium-tin-oxide (ITO) coated glass plate using electrophoretic technique. Co-immobilization of glycerol dehydrogenase (GDH) and lipase (LIP) has been done via N-ethyl-N′-(3-dimethylaminopropyl) carbodiimide and N-hydroxysuccinimide chemistry to explore its application for triglyceride (tributyrin) sensing. Response studies have been done using linear sweep voltammetry revealing that LIP-GDH/PANI-SWCNT-TB/ITO bioelectrode can detect tributyrin in the range of 50 to 400 mg dL−1 with low Michaelis–Menten constant of 1.138 mM, improved response time of 12 s, high sensitivity as 4.28×10−4 mA mg−1 dL and storage stability of about 13 weeks.
