Device for the detection and/or electrical quantification of organophosphorus compounds by means of molecular imprinting
Publication date: 2013
The present invention relates to a method and device for the detecting and/or electrically quantifying organophosphorus compounds as a gas or solution. The device includes: an electrical device including a source electrode and a drain electrode, separated by a semiconductor material; and a device for detecting positive charges between the two electrodes. One surface of the semiconductor material is in contact with a polymer material having at least one receptor group including: 1) a function X capable of reacting with the detectable organophosphorus compound, to form an intermediate grouping --Z; and 2) a function Y capable of reacting with --Z to form a positively charged ring. The polymer material includes molecular imprint cavities, with geometrical and chemical configuration allowing the detectable organophosphorus compounds to penetrate into said polymer material. The invention can be used in the field of detecting and/or quantifying organophosphorus compounds.
