Abstract
A method and device for identifying a molecule in a sample, the molecule comprising an electrophilic or nucleophilic moiety. The method comprises contacting the sample with a plurality of chemosensors, each of the chemosensors comprising a π-conjugated system and a moiety having a nucleophilic property or an electrophilic property; and measuring an electromagnetic property of each of the chemosensors in the sample; whereby the pattern of changes in the electromagnetic properties of the plurality of chemosensors after chemically reacting with the electrophile or nucleophile of the molecule identifies the molecule in said sample. The device comprises a substrate carrying a plurality of chemosensor molecules having at least one predetermined electromagnetic property, the at least one electromagnetic property being changeable by subjecting the chemosensor molecules to a sample containing at least one electrophile or nucleophile, wherein the pattern of change of the electromagnetic property of the plurality of chemosensor molecules allows the device to identify the electrophile or nucleophile in the sample.
