微流體技術因具有低成本、反應快速、低樣品消耗與所需測試樣本量較少等優勢， 因此在學術與生醫產業界均受到大量的關注。近年來，人工纖毛被認為可以有效的改 善樣品處理的模式及改變操控流體的方式，同時，人工纖毛的多功能性使得微流體裝 置有機會再更進一步的整合並微型化，於是人工纖毛逐漸被應用於微流體裝置當中。 本論文提出了多個新穎且具有發展潛力的人工纖毛微流體裝置之應用方式，透過外部 磁場驅動裝置控制人工纖毛之轉動頻率與擺動軌跡，精準的操控微流體的流動行為， 並利用微粒子影像測速儀 (Micro particle image velocimetry, μPIV) 進行微流體裝置內 的流體動力學分析，以量化微流體裝置內的流場情況。本論文所提出之磁性人工纖毛 微流體裝置能達到最高0.84的混合效率與0.089 μL/min的推進速度，除了優異的混 合與推進表現外，同時，也能使直徑 3 μm 與 8 μm 的粒子產生分離，進而達到對不 同大小粒子分類的目的，除此之外，本研究也將磁性人工纖毛結合光觸媒材料，使環 境產生光降解 (Photodegradation) 反應。本論文所提出之多種人工纖毛微流體裝置除 了能幫助生醫產業界開發靶向給藥系統 (Target drug delivery system) 與循環腫瘤細 胞 (Circulatingtumorcells) 分離裝置等新型儀器外，亦可結合本論文所提出之多種應 用方式，設計一種多功能的藥物測試系統。

Microfluidic technology has gained significant interest from the scientific community as well as biomedical industries due to its subtle advantages such as reduction in the overall processing cost, time, sample volume, energy, and reagent consumptions compared to the conventional laboratory techniques. Accordingly, artificial cilia based microfluidic devices are recent development block in the microfluidic technology and have the potential to advance the conventional methods of sample processing and fluid manipulation. In this aspect through this thesis, we are exploring the novel and potential applications of artificial cilia based devices. The motion of artificial cilia was designed to be controlled through an external electromagnetic system. For this proposed artificial cilia based microfluidic device, we have realized several potential applications such as micromixing, micropropulsion, particle separation and environmental photodegradation. Moreover, the hydrodynamics induced through the artificial cilia based device was quantified using the micro particle image velocimetry (μPIV) method. Experimental results demonstrated that a maximum micromixing efficiency of 0.84 and flow rate of 0.089 μL/min could be achieved through the proposed device. Moreover, with a slight modification of the design of the microfluidic device, the particles of the different dimension such as 3 and 8 μm can be sorted out. In addition to it, the same artificial cilia upon coated with photocatalytic materials could be used for photodegradation. These proposed microfluidic devices can be potentially used as target drug delivery system or CTCs separation device. Moreover, a multi-functionality of a single device applied to drug test system can be developed through the integration of proposed applications.
