摘要:
Metal-metal oxide electrodes provide robust and miniaturised pH sensors. Iridium oxide electrodes prepared by thermal oxidation and by anodisation are described and their relative merits discussed. The effects of chloride and protein adsorption on sensor performance are investigated using cyclic voltammetry and the mechanism by which Nation membranes can stabilise sensor response is identified. Applications in cultured intervertebral disc are reported. (c) 2006 IPEM. Published by Elsevier Ltd. All rights reserved.
