2CH-1BG. The same observations for pore volume were registered:7.00 (± 0.07) mm3g−1for 1CH-2BG scaffolds, 7.40 (± 0.07) mm3g−1for 1CH-1BG scaffolds and 2CH-1BG scaffolds present 8.10 (±0.08) mm3g−1of pore volume. It was found that the specific sur-face area and pore volume increase when the introduced content ofchitosan increases [14]. Moreover, specific surface area of 46S6 andchitosan are respectively 0.9 and 0.7 m2g−1[14]
