本論文主要探討兩種金屬氧化物（二氧化鈦及二氧化錳）之奈米顆粒，分別修飾於氧化鋅奈米管/ITO之基板上，製備非酶葡萄糖感測元件。首先以射頻濺鍍系統沉積氧化鋅種子層在ITO玻璃基板上，透過水熱法成長氧化鋅奈米柱。再以鹼性蝕刻溶液對氧化鋅奈米柱進行蝕刻，得到氧化鋅奈米管(ZnO NTs/ ITO)。另外，本研究亦合成TiO2、MnO2奈米顆粒。分別以浸塗法與滴塗法成長TiO2、MnO2在ZnO NTs上，完成浸塗之TiO2/ ZnO/ ITO、滴塗之TiO2/ ZnO/ ITO與滴塗之MnO2/ ZnO/ ITO感測元件。採用ZnO NTs結構是因為其具有穩定的奈米級形貌，能夠有效地增加待測物與電極的接觸面積。而修飾的兩種不同的金屬氧化物奈米顆粒，能夠進一步提升元件對葡萄糖的感測能力。
實驗結果得知，滴塗17.5mg之MnO2/ ZnO/ ITO感測元件對葡萄糖有最佳的靈敏度。其靈敏度為109.61μAmM-1cm-2，R2值為0.9959，線性感測範圍為0.1mM~7.0mM。此外，添加干擾物對於電流之影響小於10%，響應時間小於3秒。優異的葡萄糖感測器能更精準、快速地檢測糖尿病，在食品工業的發展上也有相當大的重要性。

In this thesis, we investigated zinc oxide (ZnO) nanotubes/ITO glass substrate decorated with two different metal oxides’ nanoparticles (TiO2 and MnO2) for non-enzymatic glucose sensors. Firstly, a ZnO seed layer was deposited on ITO glass substrate by RF sputtering system. ZnO nanorods were then grown by hydrothermal synthesis. Alkaline etching solution was prepared to etch ZnO nanorods into nanotubes (ZnO NTs/ITO). In addition, TiO2 nanoparticles and MnO2 nanoparticles were also grown in this study. TiO2 and MnO2 nanoparticles were decorated on ZnO NTs by dip coating and drop coating respectively to complete the dip-coated TiO2/ ZnO/ ITO, the drop-coated TiO2/ ZnO/ ITO and the drop-coated MnO2/ ZnO/ ITO sensing elements. The ZnO NTs structure is used because it has a stable and excellent nano-scale morphology, which can effectively increase the contact area between the analyte and the electrode. With decoration of two different metal oxides, the sensing ability to glucose is effectively improved.
The experimental results show that the 17.5mg drop-coated MnO2/ ZnO/ ITO sensing element has the best sensing performance to glucose. The sensitivity is 109.612μAmM-1cm-2, the value of R2 is 0.9959, and the linear sensing range is 0.1mM~7.0mM. The addition of interferents has an effect on the current of less than 10% and the response time is less than 3 seconds. Excellent glucose sensors for detecting diabetes is more accurately and quickly. It is also important to the development of food industry.
