| 研究実績の概要 |
We successfully prepared a new poly(2-oxazoline), poly(2-ethoxycarbonylethyl-2-oxazoline) and applied coating to several common substrate materials of medical devices including PMMA, PP, PS, PC, and PET. The small contact angle clearly indicates that our new poly(2-oxazoline) coating is more hydrophilic than PMEA coating [~25° for poly(2-oxazoline) vs ~45° for PMEA].

理由
The Institute for Materials Chemistry and Engineering (IMCE) is an international research institute at Kyushu University promoting research related to the basic science and application of the structure and functions of materials from an atomic, molecular, to supramolecular scale. Particularly, the PI is now working in Prof. Masaru Tanaka Lab. Prof. Tanaka is an expert in the field of biocompatible materials and will provide advisory suggestions for this research. The multidisciplinary and international research team is organized in IMCE.These advanced facilities and multidisciplinary and international team would lay a solid foundation to achieve the research goal.

| 今後の研究の推進方策 |
The applicant already synthesized one poly(2-oxazoline) and confirmed it can be solubilized in ethanol, allowing methanol-free operation. These preliminary results show that the proposed pseudo-peptido-coating is promising to serve as biocompatible coating for medical devices. The applicant will further control the structure of poly(2-oxazoline) and study performance in details including long-term efficacy, to find the best candidate of pseudo-peptido-coating.

| 次年度使用額が生じた理由 |
Evaluation of long-term anti-thrombogenic and anti-fouling effect and cell adhesion experiment (such as fibroblast, macrophage, and endothelial cells) need to be performed in detail.
