摘要

In aqueous, un-buffered solution at a potential where H+ is generated in a tetraethylorthosilicate sol, nm-scale deposits of silica on electrodes are formed. Inclusion of beta-cyclodextrin in the sol promotes electrochemical activity, presumably by producing channels in the otherwise-passivating film. With the additional provision of inclusion of a redox mediator, Rh-II, the electrochemical oxidation of a representative phospholipid (PL), phosphatidylcholine (PC), is demonstrated; the process occurs without the passivation that otherwise precludes the voltammetric determination of PLs. By cyclic voltammetry, current proportional to PC concentration in the range 1 - 100 mu M is achieved with the described electrode.
