Fig. 6. KGN combined with hydrogels. (A) Cumulative release of KGN encapsulated in the GelMA and HGM (host–guest macromer) hydrogels. This figure has been adapted from ref. 99 with permission from Elsevier, Copyright © 2019. (B) KGN crosslinked with PN (polyurethane nanoparticles) (i) to achieve a sustained release effect (ii). This figure has been adapted from ref. 100 with permission from Taylor & Francis, Copyright © 2018. (C) Cumulative release of KGN in drug nano box decorated HAMA hydrogels with two different concentrations of β-CD-AOI2 (HA2CD2 and HA2CD4) compared with the control group (non-decorated HAMA hydrogel).
