An amperometric biosensor for choline determination prepared from choline oxidase immobilized in polypyrrole-polyvinylsulfonate film.
In this paper, a novel amperometric choline biosensor with immobilization of choline oxidase on electrochemically polymerized polypyrrole-polyvinylsulphonate (PPy-PVS) film has been accomplished via the entrapment technique. The effects of pH and temperature were investigated and optimum parameters were found to be 9.0 and 60 °C, respectively. There are two linear parts in the region between 1.0 × 10 (-7) - 1.0 × 10 (-6)M (R(2) = 0.997) and 1.0 × 10 (-5) - 1.0 × 10 (-3) M (R(2) = 0.986). The storage stability and operation stability of the enzyme electrode were also studied.
