  • Procedure for the analysis of biological substances in a conductive liquid medium
    Patent number: 6803229
    Abstract: The present invention relates to a procedure for the qualitative and/or quantitative analysis of biological substances, which are preferably biological substances, that are present in a conductive liquid medium, with the aid of at least one affinity sensor that includes at least one structure that includes at least one semiconductor material, which is coated on one of its surface with at least one layer of an isolating material, which in turn is affixed adhesively to at least one sensitive membrane, which is in contact with the conductive medium and which includes ligands that are complementary to the biological substances in question and which are capable of, and suitable for, forming pairs specifically with the latter biological substances, with the said procedure being characterized by the fact that it consists essentially of applying a voltage between the semiconductor and the conductive medium; of gathering the variations in the electrical signals induced by a charge-effect phenomenon directly and essent
