摘要：
A chromogenic assay includes a substrate comprising an array of 5 or more dyes which react with volatile organic compounds, wherein the dyes are chromogenic when reacted with volatile organic chemical biomarkers, wherein the volatile organic chemical biomarkers comprise acids, alcohols, aldehydes, alkenes, amines, antioxidants, aromatic compounds, esters, ethylene, lactones, ketones, organosulfur compounds, sulfides, reactive oxygen species, terpenes, or a combination thereof. A method of detecting volatile organic chemical biomarkers includes contacting the chromogenic assay with a sample or sample headspace, wherein the sample or sample headspace is suspected of containing volatile organic chemical biomarkers, and identifying, based on a colorimetric pattern on the chromogenic assay after contacting, the source of the volatile organic chemical biomarkers. Also included are articles and systems including the chromogenic assay.
