Platinum Metals Review - Volume 39, Issue 2, 1995

A review of the background of biosensors which utilise osmium complexes for monitoring the glucose levels in diabetic patients is presented. An electrochemical system, based on an osmium redox polymer, is described; the system is aimed at being a reliable, compact and miniature in vivo sensor for implantation into diabetic patients for continuous monitoring of their blood glucose levels. The sensor is about to begin trials on human volunteers.

Since little has been written about ruthenium alloy plating, the present work sets out to provide data on the electrodeposition of ruthenium-cobalt alloys, using a sulphate-sulphamate electrolyte. Some operating conditions have been obtained for the production of thin crack-free coatings of ruthenium-cobult alloys.
