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 nuclephile, wherein the pattern of change of the electromagnetic property of the plurality of chemosensor molecules allows the device to identify the electrophile or nuclephile in the sample.
一种用于识别样品中分子的方法和装置,该分子包括亲电或亲核基团。该方法包括将样品与多个化学传感器接触,每个化学传感器包括一个π-共轭系统和一个具有亲核性或亲电性的基团;并测量样品中每个化学传感器的电磁性质;因此,在化学反应与分子的亲电或亲核基团后,多个化学传感器的电磁性质的变化模式可以识别样品中的分子。该装置包括一个基板,携带多个化学传感器分子,具有至少一个预定的电磁性质,至少一个电磁性质可通过将化学传感器分子暴露于包含至少一个亲电或亲核物质的样品中而改变,多个化学传感器分子的电磁性质的变化模式允许该装置识别样品中的亲电或亲核物质。
