Abstract
Current requirements for measuring applications in biotechnology and biomedical applications require the use of planar sensors or sensor arrays. Previously used techniques for preparing pH-sensitive surfaces have various disadvantages. An interesting alternative is the electroplating of such surfaces. In this work, opportunities for the galvanic deposition of pH-sensitive antimony- and bismuth-layers are presented. The properties of the deposited films in terms of suitability as a pH-sensitive surface are compared. The results indicate that both antimony and bismuth with pH-sensitive layers can be electrodeposited. The separation results can be achieved by varying the parameters and the electrolyte composition influence far reaching. The issue of long-term stability of the deposited layers requires further investigation.
