介紹

在日本東京大學工業科學研究所的生物物理工程實驗室裡，我們有一個面向博士生的開放項目。

聚二乙炔(PDA)是一種電致變色的導電聚合物。在微擾下，PDA改變了其結構，從而改變了電子帶隙，從而改變了它的光學和電學性質。這種材料有應用潛力，如生物傳感器和細胞膜力傳感器。本文結合光譜學、原子力顯微鏡和光學顯微鏡研究了PDA機械致變色的結構和基本機理。它將使我們能夠確定支配mechanochromism的關鍵參數，並設計出適用於每種應用的所需靈敏度範圍或效率的第二代聚合物。

About the Project

In the laboratory of Biophysical Engineering, the Institute of Industrial Science, at the University of Tokyo, Japan, we have an open project for PhD students.

Polydiacetylene (PDA) is a conductive polymer that has mechanochromism. Upon perturbation, PDA changes its structure, which results in altering the electronic band gap, thus its optical and electrical properties. The material has potentials for applications such as biosensors and cell membrane force sensors. We study the structure and the fundamental mechanism behind the mechanochromism of PDA by combining several spectroscopy methods, atomic force microscopy, and optical microscopy. It will allow us to determine the key parameters that govern the mechanochromism and to design the second-generation polymer that has desired sensitivity range or efficiency for each application.
