Macrocyclic host–guest design for adaptable hydrogel. a) Illustration of “pendant” architecture; b) Illustration of “threading” architecture; c) Network architectures examined included a host-guest (GH) hydrogel, covalently crosslinked (MeHA) hydrogel, GH double network (DN), and MethGH DN. Local stress under loading (red) dissipated through reversible GH complex rupture [34].

And the confocal microscopy images of cells cultured in these two kinds of hydrogel [44]. Copyright (2016) Wiley.
