	研究興趣與成果
Updated on july 30, 2014 近年研究方向偏重於長鏈高分子的統計性質及分子馬達產生運動的機制。直方向振動平台上的珠鏈會做混亂的運動，這樣運動的珠鏈的正向投影的統計性質和相變化非常像熱運動中高分子在二度空間的特性，用珠鏈的模擬使得研究高分子性質的實驗(尤其對單分子的研究) 能大幅度簡化，並可做得更仔細。我們做了珠鏈在受限制空間內運動的統計及動態性質的探討，發現珠鏈的行為完全可以用高分子的理論解釋，並且判別出最適合描述受限長鏈分子動態行為的自由能的形式，且Einstein relation在受限的珠鏈系統亦成立。另一研究方向為探討分子馬達的機制，我們採取一全新的構想，即在一有不對稱的結構上的無方向性的混亂運動可以產生有方向性的運動。這樣的構想亦適用於在角度上的不對稱結構，其可使混亂運動產生旋轉運動。這樣的構想已成功地應用在濾過性病毒將DNA包在熵很小的殼內的過程、及kinesin在微管 (microtubule) 上的運動。未來將發展到dynein在微管上的運動、ATPase的γ軸的旋轉、及其他細胞內蛋白質的有方向性的運動。
