In this work, porous tubular scaffolds were prepared from a novel water soluble aldehyde-functionalized chitosan (ALDCHIT) hydrogel, which was obtained by dissolving this chitosan derivative in water and using oxidized dextrose (OXDEXT) as the crosslinking agent at different ALDCHIT:OXDEXT mole ratios (10:1, 10:2 and 10:4). By increasing the amount of OXDEXT in respect to ALDCHIT the hydrogels became more rigid and could absorb more than 200% of its weight in water. Since the ALDCHIT:OXDEXTdoi:10.21577/0100-4042.20160124 fatcat:tevelrlmxjfdnnc2ijuhxnkdwi
