Her research is to fabricate a molecularly imprinted quantum dots (MI-QDs) for rapid detection of phenolic endocrine disrupting chemicals (EDCs). Functionalized amylose was grafted onto QDs as receptor element to sense the EDCs, including Bisphenol A (BPA), 2,2'-Bisphenol F, anthracene, phenol, pyrene, and estrone. However, the selectivity of amylose grafted QDs was weak in recognizing those EDCs. Molecular imprinting technique was applied by taking target molecule BPA as template and embedded into the cross-linked amylose grafted QDs. The MI-QDs exhibited a good selectivity in sensing BPA over those EDCs.

His research interest is to fabricate molecularly imprinted hybrid (MIH) as a selective adsorbent for Bisphenol A (BPA) removal. The MIH was prepared by coating the BPA-imprinted linear copolymer (styrene-co-methyl methacrylate) with SiO2 moieties. The organic copolymer can enhance the rebinding affinity of imprinted matrix, while the inorganic SiO2 inhibited non-specific interaction. The MIH displayed a high selectivity factor of 2-24 for BPA molecules over the other three structural analogues which implied the potential application of target-selective adsorbent for water purification.

His research is to prepare Cu(II) loaded onto weak anion exchanger resin (WAER) to efficiently remove ammonical-N (NH4+-N) from water. Cu(II) ions were first complexed with amino groups on WAER, later the Cu(II) ions served as the interaction sites for NH4+ ions adsorption based on the strong formation constant between Cu and N. The kinetic and isotherm study of Cu(II) modified WAER at different pH were investigated to realize its adsorption behaviour.

以雙酚A (Bisphenol A, BPA)作為模板開發分子拓印有機無機複合吸附材(Molecularly Imprinted Hybrid, MIH)，分析其動力吸附、等溫吸附、溶劑影響以及選擇性，並探討環境因子包括pH值、離子強度及天然有機物質對於MIH吸附BPA之影響，以瞭解BPA、MIH與環境因子三者之間的作用，找出最佳吸附條件。此外也將MIH作為固相萃取(solid phase extraction, SPE)材料，應用於不同環境水樣包括河水、湖水以及海水中，分析其萃取BPA的能力，以及搭配液相層析分析方法對降低偵測極限的貢獻，以明確MIH在SPE技術的應用潛力。

利用分子拓印技術(Molecular Imprinting)對雙酚A (BPA)製備拓印材料為接受元件，結合訊號元件光子晶體(Photonic Crystal，PC)，以開發對BPA有高選擇性之拓印反蛋白石感測器。拓印反蛋白石之感測原理為感測器在水溶液中因吸附BPA分子產生膨脹-收縮的現象，改變其光反射之波長位移量，造成反蛋白石的顏色變化且可被“視化檢測”，有利於感測器的微型化及方便攜帶性，實現即時限地應用於實際水樣之監測。
