Title (EN) MOLECULAR WIRE INJECTION SENSORS
(FR) CAPTEURS A INJECTION DE FILS MOLECULAIRES
Abstract:
(EN) Disclosed is a sensor for sensing the presence of an analyte component without relying on redox mediators. This sensor includes (16) a plurality of conductive polymer strands each having at least a first end and a second end and each aligned in a substantially common orientation; (18) a plurality of molecular recognition headgroups having an affinity for the analyte component and being attached to the first ends of the conductive polymer strands; and (14) an electrode substrate attached to the conductive polymer strands at the second ends. The electrode substrate is capable of reporting to an electronic circuit reception of mobile charge carriers (electrons or holes) from the conductive polymer strands. The electrode substrate may be a photovoltaic diode.
(FR) L'invention concerne un capteur servant à détecter la présence d'un constituant d'analyte sans employer de médiateurs redox. Le capteur comporte (16) plusieurs brins polymères conducteurs, chacun de ceux-ci comportant au moins une première extrémité et une deuxième extrémité, et chacun étant aligné suivant une orientation sensiblement commune; (18) plusieurs groupes de tête de reconnaissance moléculaire présentant une affinité pour le constituant d'analyte, et étant fixés aux premières extrémités des brins polymères conducteurs; et (14) un substrat d'électrode fixé aux brins polymères conducteurs aux deuxièmes extrémités. Le substrat d'électrode est capable de signaler à des circuits électroniques la réception de porteurs de charge mobiles (électrons ou trous) provenant des brins polymères conducteurs. Le substrat d'électrode peut être une diode photovoltaïque.
