Abstract
(A1) Ein optischer Sensor weist einen Kanal (110) und einen Lichtwellenleiter (120) auf. Der Kanal (110) weist gegenueberliegenden Seitenwaenden (112a, 112b), die durch einen Boden (114) verbunden sind, auf. Der Lichtwellenleiter (120) ist entlang der gegenueberliegenden Seitenwaende (112a, 112b) und entlang des Bodens (114) ausgebildet, so dass Licht (130) beim Passieren des Lichtwellenleiters (120) ein evaneszentes Feld (132) im Kanal (110) erzeugt und Molekuele (140) im Kanal (110) durch eine Wechselwirkung mit dem evaneszenten Feld (132) detektierbar sind.

 

DE 102009025073 A1 UPAB: 20110117 NOVELTY - The optical sensor has a channel (110) with opposite side panels (112a,112b) which are connected by a base (114). An optical fiber (120) is formed along the opposite side panels and along the base, so that a field (132) generates the light (130) in the channel by passing to the optical fiber. The molecules (140) are detected in the channel through a reciprocal effect with the field. The optical fiber is made of transparent material, particularly polymethyl methacrylate. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a method for manufacturing an optical fiber; and (2) a method for manufacturing an optical sensor structure. USE - Optical sensor. ADVANTAGE - The optical sensor has a channel with opposite side panels which are connected by a base, where the optical fiber is formed along the opposite side panels and along the base, so that a field generates the light in the channel by passing to the optical fiber, and thus ensures improved optical sensor.
