Abstract

Results are presented of implementing a new kind of optical analytical method, in which, as a sensor, membranes are used that are created of reagents immobilized on optically transparent solid polymer matrices. Interacting with a substance under investigation the immobilized reagents change the matrix color. This color change indicates a content of a component determined and persists for a long time. The color difference obtained can be transformed to numerical value that is treated as analytical information. The registration of not reflection and transmission of the light radiation through transparent sensor is promising to reach larger sensitivity up to order of magnitude 102 at low optical absorption.
