Figure 5. Schematic diagram of the bioinspired ion channel based on flexible polymer nanochannels. (A) The PI-b-P4VP-based bioinspired mechanosensitive ion channel. Upon mechanical stimulation of the membrane, the P4VP channel undergoes significant deformation. Reproduced with permission^[18].

Light induces the formation of porphyrins inside, generating surface charges that promote the formation of chloride ion channels. PI-b-P4VP: Polyisoprene-b-poly4-vinylpyridine.
