Dual Thermo- and pH-responsive Behavior of Double Zwitterionic Graft Copolymers for Suppression of Protein Aggregation and Protein Release

Dandan Zhao, Robin Rajan, Kazuaki Matsumura

Dual-thermo- and pH-responsive graft copolymers were successfully synthesized by RAFT polymerization. These of two polymers not only exhibit a dual-temperature responsive property, but also exhibit a pH-responsive property. Interestingly, a very high protein protection efficiency was observed due to the zwitterionic polymer branch. The presence of the polyampholyte structure enables these polymers to act as protein release agents, while simultaneously protecting the proteins from severe stress.

It was a great honor to receive the best research award at the conference. For this achievement, I am extremely grateful to Associate Prof. Dr. Kazuaki Matsumura and Assistant Prof. Dr. Robin Rajan for their support and guidance. Without their help, I could not finish this work. I would also like to thanks Mrs. Keiko Kawamoto and Mr. Harit Pitakjakpipop for their help in cytotoxicity assay and the taken of photographs. And last, by not least, I would like to thank all my lab members and friends for always trusting me and help me.
