Characterization of controlled highly porous hyaluronan/gelatin cross-linking sponges for tissue engineering

► Process to control with respect to the desired final pore size and structure. ► Using the salts to occupy and generate interconnective pores. ► Cross-linking the scaffolds, remove the particulate through the salt leaching process. ► Leaching amounts had primary contribution to the compressive modulus and density. ► Volumes of cross linker are crucial in water absorption abilities.
