| analysis | determination of lead ions by inhibition of choline oxidase enzyme using an amperometric choline biosensor. Choline oxidase is immobilized on a glassy carbon electrode modified with multiwalled carbon nanotubes through cross-linking with glutaraldehyde. In the presence of choline oxidase, choline is enzymatically oxidized into betaine at -0.3 V versus Ag/AgCl reference electrode, lead ion inhibition of enzyme activity causing a decrease in the choline oxidation current. Under the best conditions for measurement of the lowest concentrations of lead ions, the choline oxidase/multiwalled carbon nanotubes/glassy carbon electrode gives a linear response from 0.1 to 1.0 nM Pb2+ and a detection limit of 0.04 nM | Alcaligenes sp. |
