Fig. 7From: Accelular nanofibrous bilayer scaffold intrapenetrated with polydopamine network and implemented into a full-thickness wound of a white-pig model affects inflammation and healing processStress–strain curves of cross-linked bilayers during both dry a, b and wet c, d measurements influenced by PDA addition. Collagen foam with cross-linked nanofibers is represented as Coll-N; collagen/chitosan foam with cross-linked nanofibers is represented as Coll/Chit-N; and collagen/oxidized cellulose foam with cross-linked nanofibers is represented as Coll/CaOC-N. The mark ‘PDA’ represents additional polydopamine coating on bilayerBack to article page
