Abstract
Description
本開示は、一般にはアナライザに関するものである。アナライザを用いて検知を行うための方法もまた本明細書内において開示されている。
本明細書内において開示したアナライザの実施形態は、導波路と流体チャンネルとを単一基板内へと有利に統合し、それにより、実験(lab)オンチップセンサ設計が提供される。(本明細書内においてV字グルーブとしてもまた呼ばれる)V字型グルーブは、光が該V字型グルーブを通じて検出されるものであり、流体チャンネルの一部分と合致するように構成され、従って流体がそこを通じて流れるように構成されている。V字型グルーブと流体チャンネルとの統合は、流体サンプル(複数可)と相互作用させるためのかなりの空間を光に有利に提供する。アナライザ内において起こる光と液体の相互作用の量が、結果として有利にプラズモン増強(plasmonic enhancement)を生じさせて信号出力を増大させるということが信じられている。
