Abstract
Description
感染症および他の内科的疾患は、継続的に人の生命に影響を及ぼす。例えば、患者の病気を診断するために、血液中または他の流体(体液)中の抗原の存在を検出するための開発が行われた。場合によっては、マイクロ流体デバイスを用いて、被検物質(検体)を分析する。
上述したように、マイクロ流体診断チップ(MDC)のようなマイクロ流体デバイスは、被検物質を含む流体を受け取り、流体内の病原体または他の異常を検出する。MDCを実現することに対する代案は、被検物質を含む流体のサンプル(試料)を採取して、分析のための研究室にそのサンプルを移送することである。この分析プロセスは、サンプルを適切に処理するために、デリケートで高価な試薬を用いて一連の正確な工程を行う技師を必要とする。試験を実行する人は通常、当該分析を行うために特別に訓練されている。
