β¦ Synopsis
A glucose probe based on a suitable modification of the silanization process of commercially available polycarbonate membrane was assembled and evaluated. The silanization procedure was carried out in gaseous phase in an anhydrous atmosphere, with dimethyldichlorosilane in a closed vessel. This new procedure seems to be highly reproducible and has the distinct advantage of fast response time and extended linearity up to 0.1 mol l-1 of glucose. Application to serum samples shows the possibility of application in clinical chemistry.

Whole cells of Aspergillus niger strain CCM 8004 containing glucose oxidase (EC. 1.1.3.4.) were used for the preparation of a glucose biosensor. The microorganism was entrapped in a dialysis membrane attached to the Clark oxygen electrode. The upper linearity limit of the sensor was improved by the
