Working scheme of DNA aptamer circuit on cell membrane. (a) Scheme of the circuit without catalyst. (b) Scheme of the circuit on the cell membrane. (c) Scheme of detailed reaction of DNA hairpins A1 and A2 catalyzed by C sequence. Different domains are labeled with different colors. All x domains are complementary to x* (adapted from Han et al.66).
