Abstract
A device for detecting and/or quantifying organophosphorus compounds, including an electrical device including a source electrode and a drain electrode separated by a semiconductive material, characterized in that at least one receptor molecule, including a group R and a primary alcohol in spatial proximity to a tertiary amine, with which the primary alcohol is capable of reacting in the presence of an organophosphorus compound, is grafted, by the group R, onto one of the electrodes or onto the semiconductive material, and a device for detecting the variation in positive charges between the two electrodes.
Claims15
An apparatus for detecting and/or quantifying organophosphorus compounds, comprising:
- an electrical device comprising a source electrode and a drain electrode separated by a semiconductive material, wherein at least one receptor molecule, comprising a group R and a primary alcohol in spatial proximity to a tertiary amine, with which the primary alcohol is capable of reacting in the presence of an organophosphorus compound, is grafted, by means of the group R, onto one of the source or drain electrodes or onto the semiconductive material, and
- a device for detecting the variation in positive charges between the two electrodes, wherein
- the at least one receptor molecule has the general formula:
- in which R is a group comprising a function that enables the at least one receptor molecule to be grafted onto at least one of the source electrode, the drain electrode and the semiconductive material.
