Supramolecular guest-host hyaluronic acid bioinks. Physically crosslinked guest-host HA hydrogels can serve as sacrificial bioinks while methacrylated guest-host HA hydrogels can be covalently crosslinked by UV to form a mechanically stabilized bioink. Sacrificial guest-host HA bioinks can be embedded within stabilized guest-host MeHA hydrogels to fabricate a perfusable network (scale bar = 500 μm). Adapted with permission from ref. 502.
