Here we report the biomimetic polymer that causes self-oscillation driven by the addition of biorelated organic acid. We constructed the built-in system where all of the substrates of the BZ reaction other than biorelated organic substrates were incorporated into the polymer chain. The quarternary copolymer, which includes both of the pH-control and oxidant-supplying sites in the poly(N-isopropylacrylamide-co-Ru(bpy)3) chain was synthesized. By using the polymer, we first succeeded in causing the self-oscillation of the polymer only in the coexistence of organic acid.
