Summary: | To provide a biosensor that includes a device base having a sensor array of a light sensor and a guide array of a light guide.SOLUTION: A light guide 462 has an input region 472 that is configured to receive excitation light 401 and light emission 466 generated by a biological or chemical substance. The light guide extends into the device base toward corresponding light sensors from the input region and have a filter material 460. The device base includes a device circuit that is electrically coupled to the light sensor and configured to transmit a data signal. The biosensor further includes a shield layer 450 that has an aperture 452 positioned with an input area of corresponding light guides as a reference, and is configured such that the light emission propagates into the corresponding input regions through the aperture. The shield layer extends between adjacent apertures, and is configured to block the excitation light and the light emission incident upon the shield layer between the adjacent apertures.SELECTED DRAWING: Figure 9
【課題】光センサのセンサアレイと、光ガイドのガイドアレイとを有する装置ベースを備えたバイオセンサを提供する。【解決手段】光ガイド462は、励起光401および生物学的または化学的な物質により生成される光放射466を受け取るように構成した、入力領域472を有する。光ガイドは、入力領域から対応光センサに向かって装置ベース内に伸長し、フィルタ材460を有する。装置ベースは、光センサに電気的に結合し、データ信号を送るように構成した装置回路を備える。バイオセンサはまた、対応光ガイドの入力領域を基準にして位置決めした開口452を有し、光放射が開口を通って対応入力領域に伝播するようにしたシールド層450を備える。シールド層は隣接開口間を伸長し、隣接開口間のシールド層へ入射する励起光および光放射をブロックするように構成される。【選択図】図9 |
