Sensor element and method for making the same.

摘要

A sensor element (10) includes an analyte-permeable matrix (16) which supports and maintains a sensing solution containing an analyte-sensitive indicator substance in a plurality of tiny vesicles (18). The sensor element (10) is prepared by combining the sensing solution remains suspended in these dispersed vesicles (18) after the matrix solidifies. A sensor element (10) made in accordance with the present invention may be placed at the end of an optical fibr (14).
