Biosensor und ein Verfahren zum Messen einer Konzentration eines Analyten in einem Medium

(A1) Ein Biosensor zum Messen einer Konzentration eines Analyten (110) in einem Medium (120) umfasst einen elektrischen Ladungsspeicher (130) und eine Widerstandsschicht (140) mit einem elektrischen Widerstand, der sich bei Kontakt zu dem Analyten (110) aendert. Der elektrische Ladungsspeicher (130) weist eine Sensorelektrode (132) auf und die Widerstandsschicht (140) ist in Kontakt zu dem Medium (120) bringbar und derart zwischen dem Medium (120) und der Sensorelektrode (132) angeordnet, so dass im Kontakt mit dem Medium (120) eine Anzahl der in dem elektrischen Ladungsspeicher (130) gespeicherten elektrischen Ladung (142) die Widerstandsschicht (140) passiert.

US 20090066347 A1 UPAB: 20090403 NOVELTY - The biosensor has an electrical charge storage (130) including a sensor electrode (132), and a resistive layer (140) including an electrical resistance, which changes upon contact with an analyte (110). The resistive layer contacts a medium (120) e.g. solution, and is arranged between the medium and the sensor electrode during contact with the medium. A number of electrical charges (142) stored in the electrical charge storage passes through the resistive layer. A measurer (150) measures an effect of the electrical charge existing on the sensor electrode or leaking off. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a method for producing a biosensor for measuring a concentration of an analyte within a medium (2) a method for measuring a concentration of an analyte within a medium. USE - Biosensor e.g. ultra-sensitive complementary metal oxide semiconductor biosensor, for measuring a concentration of an analyte within a medium e.g. solution, foodstuff, and environmental pollution. Uses include but are not limited to chemical biosensor, potentiometric and conductometric biosensor, optical biosensor, and micro gravimetric and calorimetric biosensor. ADVANTAGE - The resistive layer contacts the medium and is arranged between the medium and the sensor electrode during contact with the medium, and the number of the electrical charges stored in the electrical charge storage passes through the resistive layer, thus allowing the biosensor to be easily handle with highly sensitive.
