为了创建一个纳米级的双开关，两个响应的DNA基序，偶氮苯修饰的DNA和G-端粒重复序列，一起引入到纳米框架系统。利用高速原子力显微镜（AFM）成功地实现了由光辐射和K+控制的双开关行为的真实的实时可视化。
To create a nanoscale dual switch, two responsive DNA motifs, azobenzene-modified DNAs and G-telomeric repeat sequences, were introduced together into the nanoframe system. The dual-switching behaviors controlled by photoirradiation and K+ were successfully visualized in real time by high-speed atomic force microscopy.
