Abstract
The optimal conditions to prepare water-soluble, stable poly(acrylic acid)-wrapped multiwalled carbon nanotubes (PAA-MWNTs) complex is presented. PAA-MWNTs shows high stability within weak acid to weak basic pH condition. The complex also shows good endurance to moderate ionic strengths in the buffer solution. The PAA-MWNTs complex film-covered electrode demonstrates stable, excellent electrocatalytic activity to oxidize NADH, which makes it possible to prepare NADH sensor at a low potential of ∼0.13 V (versus Ag/AgCl) with the linear range of 4–100 μM by differential pulse voltammetry.
