本發明係揭露一種雙面光柵波導生物感測器,用以檢測ㄧ待測物之性質,其中雙面光柵波導生物感測器包含依序堆疊之具有光柵部之塑膠光柵、具有雙面光柵結構之波導層及流道晶片。並且,流道晶片係導入有待測物,其中當一光線藉由雙面光柵結構耦合入波導層,並於波導層中傳遞時,本發明之雙面光柵波導生物感測器藉由穿透出波導層之光線之光強度之變化,以檢測此待測物之性質。此雙面光柵波導生物感測器以高分子轉印成型及薄膜沈積技術製造,使能大量生產且降低成本。 A double sided-grating waveguide biosensor is disclosed. The double sided-grating waveguide biosensor is used to sense the properties of the sample solution. The double sided-grating waveguide biosensor comprises a plastic grating having a grating part, a waveguide layer having a double sided-grating structure and a channel chip stacked on the plastic grating. Besides, the sample solution is guided into the channel chip, the light is coupled into the waveguide layer by the double sided-grating structure, transmitted in the waveguide layer, and ejected, such that the properties of the sample solution can be detected according to the change of the coupling intensity.
