Fabrication and Characteristics of Chitosan Sponge as a Tissue Engineering Scaffold

Table 1

The mechanical properties of sponges with different concentrations of chitosan in the wet state (average ± standard deviation of at least five samples).

Type of sponge	Tensile strength (Mpa)	Young's modulus (Mpa)
1 wt%	0.07±0.01^Ab	0.05±0.02^Bb
2 wt%	0.12±0.03^Ac	0.23±0.06^Bc
4 wt%	0.44±0.08^Ad	2.02±0.11^Bd
Gelatin	0.03±0.01^Aa	0.02±0.02^Ba

Different superscript letters indicate statistically significant differences between groups (𝑃<0.05).
