Preliminary Characterization of Genipin-Cross-Linked Silk Sericin/Poly(vinyl alcohol) Films as Two-Dimensional Wound Dressings for the Healing of Superficial Wounds
Figure 4
In vitro release profiles of silk sericin from the films cross-linked with genipin at different concentrations: (○) 0, (•) 0.01, (▲) 0.025, () 0.05, (■) 0.075, and (*) 0.1% w/v after incubated in a phosphate-buffered saline solution (PBS, pH 7.4) at 37°C and assessed by a BCA protein assay kit. *, significant against the values of non-cross-linked films at corresponding time.
