MATRIX TRANSDUCER TO DETECT ANALYTES IN LIQUIDS Russian patent published in 2000 - IPC

FIELD: detection of analytes in liquids in combination with measuring devices. SUBSTANCE: given invention refers to methods, devices and testing systems for detection of analytes in liquids. Matrix transducer to detect analytes is assemblage of chemical pickups different in composition. Each pickup includes first and second conducting elements electrically bonded to chemically sensitive resistor which ensures path between conducting elements. Resistor has collection of alternating non- conducting sections which include non-conducting organic polymer and of conducting sections which include conducting material. Electric current path between first and second conducting elements passes through specified collection of alternating non- conducting and conducting sections. Resistor provides for difference of resistance between conducting elements while they contact liquid. Analyte detection system incorporates electric measurement device electrically connected to specified matrix transducer, matrix transducer and computer with resident algorithm. EFFECT: matrix transducers are simple in manufacture, are capable of reaction to wide range of analytes and their signals are easily integrated in software or in neural nets. 10 cl, 18 dwg, 4 tbl
