ABSTRACT:
A composition of matter useful in a sensor for sensing the concentration of an ionic component in a medium is disclosed. This composition comprises a first material which includes a sensing component in an amount effective to provide a signal which varies as the concentration of the ionic component in the medium varies, and a first matrix material which is permeable to the ionic component; and a second material which includes a second matrix material which is permeable to the ionic component, and an opaque agent in an amount sufficient to render the second material effectively opaque. The first material matrix and the second matrix material are covalently bonded together. Sensing apparatus including such composition of matter and methods for making and using such composition of matter are also disclosed.
