The Hydrophobic Effect on Electrodeposition of Billirubin Oxidase CotA

Abstract:

The hydrophobic effect on electrodeposition of an enzyme CotA was investigated. The CotA was electrodeposited on a gold disc electrode modified with an alkane thiol self-assembled monolayer (SAM). The CotA immobilized hydrophobic SAM gold electrodes exhibited a larger electrochemical activity compared with the hydrophilic SAM and bare electrodes. In particular, large current responses were observed in an ethanethiol or a 1-butanethiol SAM gold electrode. In addition, effect of addition of non-ionic surfactant Triton X on the electrodeposition was checked using the SAM gold electrode. The addition of Triton X had a positive effect on the electrodeposition.
