Figure 7. Illustration of the butterfly-shaped and pillar-shaped bioinspired mechanosensitive ion channel. (A) The mechanosensitive butterfly-shaped K-channel. Mechanical stimulation will accelerate the K⁺ transport of GnC7. Reproduced with permission^[19]. Copyright 2025, Wiley-VCH; (B) The crown ether aggregate membrane for the K channel. During the resting state, K⁺ is selectively transported. When ΔP is loaded, the direction and rate of the ion flow reverse.^[108] Copyright 2026, The American Association for the Advancement of Science. GnC7: Mechanically and pH dual-gated butterfly-shaped artificial ion channel; PB: polybutadiene; CA: crown-aggregate; UPy: terminal 2-ureido-4-pyrimidinone ΔP: pressure difference.
