Abstract

A system and associated method for determining the presence of a reactive compound in an analyte, including a membrane having a plurality of channels or pores having surfaces affixed with one or more of functionalized nanoporous materials, antibodies, and proteins capable of reacting with the reactive compound in the analyte and changing the porosity of the membrane from a first porosity to a second porosity; a fluid source for contacting the membrane with a fluid; a gasochromic material configured such that a portion of the fluid in contact with the membrane flows through the plurality of channels or pores and contacts the gasochromic material; an excitation source capable of exciting the gasochromic material to generate an emission; a detection device capable of detecting the emission; and a processor configured to process data obtained by the detection device corresponding to the first porosity or the second porosity of the membrane.
