Patent number: 9856446Abstract: The present invention is an apparatus for detecting the presence, quantity and identity of one or more microorganisms in a sample and a method for using the same. The apparatus is composed of one or more chambers and a sensing element for sensing microorganisms. In particular embodiments, the sensing element is an array of chemoresponsive dyes deposited on a substrate in a predetermined pattern combination, wherein the combination of the dyes have a distinct and direct spectroscopic, transmission, or reflectance response to distinct analytes produced by the microorganism which is indicative of the presence, quantity and identity of the microorganism.Type: GrantFiled: January 12, 2016Date of Patent: January 2, 2018Assignee: THE BOARD OF TRUSTEES OF THE UNIVERSITY OF ILLINOISInventors: Kenneth S.
