Abstract

L'INVENTION SE RAPPORTE A UN DISPOSITIF DE DETECTION DE FLUX IONIQUES DESTINE A METTRE EN EVIDENCE DES VARIATIONS DANS LA CONCENTRATION EN CATIONS MINERAUX OU EN CERTAINES SUBSTANCES ORGANIQUES DANS LES TISSUS. LE DISPOSITIF EST CONSTITUE PAR UNE MICRO ELECTRODE PORTANT UN ORIFICE A SON EXTREMITE EFFILEE ET TROIS MOYENS D'AMENEE DISPOSES SELON UN AXE LONGITUDINAL ET CONVERGENT VERS LA POINTE. CES MOYENS D'AMENEE SONT DEUX CANAUX DE MESURE (UN ELECTRIQUE ET UN LUMINEUX) ET UN CANAL D'ACTIVATION (ELECTRIQUE OU MUMINEUX). LE DISPOSITIF SELON L'INVENTION TROUVE UN EMPLOI POUR LA MISE EN EVIDENCE DES CONCENTRATIONS EN CATIONS TELS QUE LE CALCIUM OU LE MAGNESIUM DANS LES TISSUS.
