In the version of this Article originally published, the authors mistakenly failed to include the following key reference: Chen, L. et al. Chiral selective transmembrane transport of amino acids through artificial channels. J. Am. Chem. Soc. 135, 2152–2155 (2013). This has now been added as ref. 12 and subsequent references have been renumbered. The new reference has been cited in the following sentences: (1) “Achieving both AQP-like single channel water permeability...”; (2) “It has been reported that the permeability of...”; (3) “These results are similar to our recent study that demonstrated...”; and (4) “Therefore, the unimolecular AWC PAP[5]...”, as well as in Fig. 2c caption “Comparison of the calculated single channel permeability...”. These changes have been made in the online versions of the Article. © 2020, The Author(s), under exclusive licence to Springer Nature Limited.
