Fabrication of Layer-by-Layer Assembled Biomimetic Nanochannels for Highly Sensitive Acetylcholine Sensing

Channel tunneling: We have prepared functional biomimetic nanochannels in polyethylene terephthalate (PET) polymer films (see illustration). We used p‐sulfonatocalix[4]arene to modify the channel surface by flexible layer‐by‐layer electrostatic assembly. Using this method we were able to detect acet...

Zusammenfassung:Channel tunneling: We have prepared functional biomimetic nanochannels in polyethylene terephthalate (PET) polymer films (see illustration). We used p‐sulfonatocalix[4]arene to modify the channel surface by flexible layer‐by‐layer electrostatic assembly. Using this method we were able to detect acetylcholine with high sensitivity.
