Gas sensor and methods for making and using same.

摘要

A sensing element for sensing the concentration of an analyte in a medium is disclosed. The sensing element comprises a matrix material having at least one indicator component covalently bonded thereto. The indicator component is capable of providing a signal dependent on the concentration of the analyte in the medium. The indicator component is derived from at least one indicator compound to which is bonded a group including a functional portion which is isolated from the at least one indicator compound. <IMAGE>
