Abstract: A method and device are disclosed for continuously detecting, classifying and identifying toxic particles, aerosols and/or vapor in an air sample, in near real time by directing an air sample containing an optional target analyte, in the form of particles, aerosols and/or vapors, enzyme(s), and enzyme substrate(s), to a surface of a collection matrix for forming a biocatalytic reaction product of a plurality of freely mobile optical reporters, and by using a light source with optical reader to interpret the signal from the optical reporter, enabling the detection, classification and identification of toxic particles, aerosols and/or vapor in the air sample.
