本研究以鍍上金面的懸臂樑為基材,利用自聚性覆膜技術,開發一種高靈敏度之氣相懸臂樑化學感測器。
首先,對懸臂樑感測平台進行穩定性及再現性測試。測試結果可知,系統達穩定後的雜訊範圍在±50 nm,而且不同探針於相同覆膜條件進行檢測,皆有一致的結果,顯示此平台的穩定性及再現性是確立的。
接著,利用此平台對自聚性成膜進行即時的檢測。實驗中以4-mercapto-1-butanol作為自聚性單分子層,即時披覆於懸臂樑上,並利用光學系統偵測其覆膜的動態變化。實驗結果得知,懸臂樑偏移量與通入的硫醇濃度呈正比關係。利用此平台進行硫醇氣體濃度的辨識,求得懸臂樑對於此硫醇分子的靈敏度為2.67 nm/fraction。
最後,在懸臂樑表面修飾羥基硫醇分子,並且對醋酸和乙醇進行檢測。實驗結果可知,懸臂樑表面修飾羥基的自聚性薄膜,對於醋酸氣體有很高的靈敏度(9.21008 nm/fraction)。由此得知,可以利用修飾不同的官能基提升感測器對特定氣體偵檢的性能。
In this study, microcantilever chemical sensors were built using Au-coated microcantilevers as the substrate, on which a self-assembled monolayer (SAM) were functionalized. They were then applied in gas sensing.
First, the stability and reproducibility of the sensing platform were tested. The results show that the noise of a stable system was between ±50 nm, and the formation of SAM under the same conditions was reproducible. Therefore, the stability and reproducibility of the sensing platform are confirmed.
Then, the formation of SAM on microcantilevers was detected in situ. In the experiments, 4-mercapto-1-butanol was functionalized on Au-coated microcantilevers to form a SAM, and the transient behavior of the SAM formation was detected using a photo-detection system. The results show that the deflection was linearly proportional to the concentration of 4-mercapto-1-butanol. Using this sensing platform for the detection of 4-mercapto-1-butanol concentration, the sensitivity was found to be 2.67 nm/fraction.
Finally, the microcantilevers functionalized by the SAM possessing a hydroxyl terminal group were used in the detections of acetic acid and ethanol, respectively. The results show that the hydroxyl terminal group SAM was sensitive to acetic acid (9.21008 nm/fraction), but not to ethanol. It is concluded that the selectivity of functionalized microcantilevers for gas sensing can be determined by properly choosing their SAM pattern.
