Аннотация:
The effect of the treatment of hydrogel matrices based on allyl-substituted chitosans and formed by laser stereolithography in supercritical carbon dioxide (SC-CO 2 ) on their surface polarity and mechanical characteristics was studied. Treatment in a flow mode increased the mechanical stability of the materials due to the effective extraction of the low-molecular components and oligomers. The surface polarity of the matrix decreased, improving its biocompatibility. The hydrogel matrices treated in SC-CO 2 have no cytotoxic activity, due to which they can be used in tissue engineering. © 2018, Pleiades Publishing, Ltd.
