18. In other SCKs, it has been found that conformational changes result when the core chains are well-solvated, leading to an inverted SCK from permeation of the chains through the shell and presentation to the external cage surface (unpublished results).

20. Nominal cross-linking is the theoretical extent of cross-linking that could occur, based upon the amine-to-carboxylic acid stoichiometry. Solid-state NMR is used to determine the conversion of carboxylic acid groups to amides; however, whether those amide groups are part of an intrachain loop vs an interchain cross-link is not known.

22. Note: the SCKs were dialyzed (molecular weight cutoff MWCO 12 000-14 000) against deionized water for 10 days.
