Progress towards in vivo glucose sensing with a ferrocene-mediated amperometric enzyme electrode.


A range of miniature, amperometric enzyme electrodes have been constructed using the principle of mediated transfer of electrons. Ferrocene, or one of its derivatives, can be used in conjunction with immobilised glucose oxidase to produce sensors which are linear to at least 20 mmol/l glucose, have fast response times, are relatively oxygen insensitive and… (More)
