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 focus on structural design and fabrication of molecularly imprinted hybrid (MIH) for the selective adsorption of endocrine disrupting chemicals (EDC). EDC such as Bisphenol A (BPA) was selected as the template model to fabricate the MIH, the synthesis of MIH begins with imprinting BPA molecules in phenyl-based linear copolymer and latter coupling with inorganic polymer such as silica dioxide (SiO2). From his study, the role of organic copolymer was meant to enhance the hydrophobic affinity and selectivity towards BPA molecules, while the SiO2 was to protect the imprinting structures and inhibit non-specific interactions. Furthermore, he also studies the molecular recognition behavior/patterns of MIH for various kinds of EDCs in terms of size, shape/geometry, and functionality.

Reserch interest : Cu(II) loaded weak anion exchanger(WAER) is prepared to efficiently remove ammonical-N (NH4+-N) from water. The kinetics, isotherm study of the Cu(II) modified WAER were investigated at different environmental condition like pH, NH4+ concentration etc. The isotherm study suggested that removal increases with increase of pH and maximum removal capacity is found as 10.04 mg/g at pH 8.04.Langmuir isotherm (R2 > 0.98) model was the best fitted model compare to Freundlich isotherm (R2 > 0.86) It is also found that rate of removal kinetics follows second order rate kinetics and it increases with pH as well as initial NH4+ concentration and max rate of removal as 0.0368 g/(mg-min). Also equilibrium is reached within 40 min.

利用分子拓印技術(Molecularly Imprinting Technology, MIT)結合光子晶體(Photonic Crystal, PC)，開發針對特定目標分子檢測之感測器。研究中先以分子拓印高分子聚合物探討材料對於塑化劑的吸附效果及吸附行為，再以此製備成附著於基材表面且呈現大規模規則有序列排列的分子拓印反蛋石感測器，藉由拓印孔洞與目標分子結合的專一性，在水溶液中產生溶脹-收縮的現象，通過波長位移量的改變，導致晶體顏色變化可作為“可視化檢測”。針對各感測器對目標分子的響應時間、辨識能力、線性範圍、最低偵測極限，與重複使用性進行研究，開發一個以玻片做為基材的感測器，以實現感測器的微型化及方便攜帶性，以實現即時限地應用於實際水樣之監測。
