Preliminary Characterization of Genipin-Cross-Linked Silk Sericin/Poly(vinyl alcohol) Films as Two-Dimensional Wound Dressings for the Healing of Superficial Wounds

Table 2

Tensile strength and percentage of elongation of silk sericin/PVA films cross-linked with genipin at different concentrations (0, 0.01, 0.025, 0.05, 0.075, and 0.1% w/v).

Genipin concentration; (% w/v)	Tensile strength (N/mm^2)	Elongation (%)
Sofra tulle	26.41±2.59	11.07±1.71
0	4.97±0.59	188.54±55.22
0.010	4.66±0.72	156.50±31.93
0.025	5.82±0.91	198.68±55.64
0.50	7.14±0.57^∗	309.60±63.36^∗
0.075	8.17±2.15^∗	331.98±55.02^∗
0.100	9.17±1.37^∗	361.98±53.85^∗
