    Abstract: The invention relates to a detector or sensor for the detection of chemical species or photons. This detector uses a field effect transistor having a semiconducting material substrate (1) in which are defined a source (3) and a drain (5), a gate (9) separated from the substrate by an insulating layer, an external energy source for polarizing the drain, source and gate of the transistor, a film (11), which is conductive or which can be rendered conductive and which is sensitive to the chemical species or photons to be detected, and an ammeter for measuring an electric current variation of the transistor. The arrangement of the film (11) between the connections of the gate (9) and the drain (5) makes it possible to modify the polarization voltage of the transistor gate under the effect of the species to be detected, which is represented by a variation of the current between the drain and the source, when the transistor is correctly polarized.

    Abstract: Process for producing a film having at least one monomolecular layer of non-amphiphilic molecules.This process comprises the following stages:(a) combining non-amphiphilic molecules A, such as pyridine, with amphiphilic molecules B, such as a zinc porphyrin, in order to form a complex of molecules A and B;(b) forming on the surface of the liquid a monomolecular layer of the thus obtained complex, and(c) transferring the thus formed monomolecular layer to a rigid support.Molecules A and B can form between them a charge transfer complex, e.g. TCNQ-alkyl pyridinium which makes it possible to obtain laminated structures of organic conductors.

    Abstract: The material comprises a membrane constituted either by at least one monomolecular layer of amphiphilic molecules, or by amphiphilic molecules adsorbed on a substrate, and microaggregates of the metal, inorganic compound or organometallic compound retained on or in the membrane. It is prepared from a membrane containing a metal ion or a precursor compound of said metal, inorganic compound or organometallic compound, by reacting the ion or precursor compound fixed in the membrane with at least one reagent for forming the metal, inorganic compound or organometallic compound in situ in the membrane. For example, the membrane can be constituted by monomolecular layers of behenic acid, which is then converted into silver behenate by contacting with a silver nitrate solution. Silver microaggregates are then formed in the membrane by reducing the silver behenate by means of hydrazine.
