DEVICE FOR THE DETECTION AND/OR ELECTRICAL QUANTIFICATION OF ORGANOPHOSPHORUS COMPOUNDS BY MEANS OF MOLECULAR IMPRINTING

摘要

The present invention relates to a method and device for the detection and/or electrical quantification of organophosphorus compounds in a gaseous state or in a solution. The device of the invention includes: an electrical device including a source electrode and a drain electrode that are separated by a semiconductor material; and a device for detecting positive charges between the two electrodes. One of the surfaces 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 organophosphorus compound to be detected, so as to form an intermediate grouping -Z; and 2) a function Y capable of reacting with said grouping -Z so as to form a ring having a positive charge. Said polymer material includes so-called molecular imprint cavities, the geometrical and chemical configuration of which allows the organophosphorus compounds to be detected to penetrate into said polymer material. The invention can be used in particular in the field of detecting and/or quantifying organophosphorus compounds.
