Enhanced scattering membranes for improved sensitivity and signal-to-noise of optical chemical sensors, fiber optic oxygen sensor for real time respiration monitoring utilizing same, and method of using sensor

摘要

This invention relates to the field of optical chemical sensors which utilize indicator molecules to detect a particular analyte in a sample, wherein the indicator molecules produce a detectable response when exposed to the particular analyte to which the indicator molecule is sensitive. Specifically, this invention relates to the use of a matrix embedded within a membrane, where the matrix enhances the scattering of light and serves as a support which provides superior mechanical strength. The invention also relates to methods of using the improved sensor in conjunction with fiber optic probes.
