Abstract
A stabilized bio-inert sensor for the determination of an analyte, especially pO.sub.2, pCO.sub.2 and pH, in a medium which comprises a chemical indicator sensitive to the analyte in association with a stabilizing substrate formed from a polymer which is inert to the medium and analyte and does not affect the sensitivity of the indicator, which polymer is a cross-linked, solid silicone rubber formed from a silicone carbinol having a molecular structure compatible with said indicator.
