✦ Synopsis

69

Simple strip type enzyme electrodes prepared from platinised Vulcan XC-72 carbon particles using silk screen printing techniques are described. Such electrodes combine the efficient electrocatalytic activity of metal microparticles with the attractive features of mass produced screen printed sensors. Immobilisation of glucose oxidase to the surface of the particles allows coupling of the biocatalytic reaction with the electrocatalytic oxidation of the liberated peroxide, thus providing a sensor for glucose with a detection limit of 2 X lo-' M.
