摘要：
A sensor chip is useful to detect a medicine releasable from a solid in a solution. The sensor chip comprises a housing unit and a sensing electrode unit. The housing unit includes a micro-channel, a partitioning piece, an extraction hole and a medicine injection hole. The micro-channel has a measure region, an injection region and an extraction region. The partitioning piece is provided in the injection region of the micro-channel. The extraction hole is connected to the extraction region, and the medicine injection hole is connected to the injection region. The partitioning piece prevents the solid which is injected from the medicine injection hole from flowing into the measure region with the solution. The sensing electrode unit is formed in the housing unit and has a working electrode disposed in the measure region. The working electrode has a conducting layer, a carbon nanotube layer electrophoretically deposited on the conducting layer and a plurality of gold nano-particles sputteringly deposited on the carbon nanotube layer.一種感測晶片適合與一含可釋放待測藥物之固體物的溶液結合使用,感測晶片包含一殼體單元及一感測電極單元。殼體單元包括一微流道、一隔離件、一抽取孔及一藥物注入孔,微流道具有一量測區、一注入區及一抽取區,隔離件設於微流道的注入區內,抽取孔連通抽取區,藥物注入孔連通注入區,隔離件阻隔固體物由藥物注入孔注入之後,受溶液流動而隨溶液被帶至量測區。感測電極單元形成於殼體單元內,並包括一曝露於量測區內的工作電極,工作電極包括一導電層、一電泳沉積於導電層上的奈米碳管層,以及複數濺鍍於奈米碳管層上的奈米金粒子。100...感測晶片2...殼體單元21...上蓋體211...基板212...第一蓋體部213...第二蓋體部214...抽取孔215...藥物注入孔216...緩衝液注入孔217...工作電極區域218...參考電極區域219...輔助電極區域22...下殼體221...基壁222...肩部223...分隔壁224...注入區壁225...微流道226...量測區227...注入區228...抽取區23...隔離件231...間隙3...感測電極單元31...參考電極32...輔助電極33...工作電極311、321...導電層
