(1)上部偏光素子および他の偏光素子を用いることにより、フォトダイオードが励起光を受光するのを防止することができる。
(2)さまざまな励起光を対象とするさまざまなバイオセンサまたはバイオ検出システムを設計せずとも、本発明の1つのバイオセンサまたは1つのバイオ検出システムは、さまざまな励起光をブロックするのに十分である。
(3)1つのバイオセンサまたは1つのバイオ検出システムでさまざまな励起光を十分にブロックするため、様々な波長の励起光を用いることができる。蛍光マーカーは、それぞれの最適な励起光によって励起されることができる。従って、得られた信号の強度は実質的に同じであり、信号の分析を容易にする。
