    • Based on this model, the distance between two surface OH groups is 5.3 Å. Thus, the number of surface OH groups around one nanopore (nanopore diameter 2.2 nm) is 13. Since the attachment of one stalk on the nanopore requires at least 2 OH groups on the nanopore perimeter, the maximum number of stalks that can become attached to one nanopore is about 6. For a fully assembled nanovalve, the size depends on the β-cyclodextrin-the periphery diameter of the secondary side is ∼1.5 nm
