Figure 7. Dynamic crosslinking of macromolecular thiols with gold nanoparticles.
(A) Au-NPs act as multivalent crosslinkers for thiol-modified HA. (B) Bioprinting consists of deposition of acellular AuNP-CMHA-S gels (blue) and cell-containing AuNP-CMHA-S/Gelatin-DTPH gels to produce a cylindrical structure. (C) A tubular cellularized construct printed without the central core outer annulus of the acellular gel. Partially reprinted with permission from [66].
