The function of biomimetic self-oscillating polymer and analysis of viscosity self-oscillation

We have been studying novel self-oscillating polymer by copolymerizing the catalyst for the BZ reaction with thermosensitive polymer. In order to cause the self-oscillation under biological condition without using non-biorelated BZ substrates, we attempted to introduce pH control domain and oxidizing agent into the polymer. As a result, we have firstly succeeded in causing the self-oscillation under biological condition in which only one BZ substrate (malonic acid) exists. From the analysis of self-oscillating behaviors, it was clarified that the waveform and period changed with the concentration of the malonic acid. Moreover, we succeeded in measuring the viscosity oscillation for the polymer solution.
