Physical characteristics (total porosity, average pore size and elasticity) of a standard, b approach 1 (without gelatin), c approach 2 (changes freezing time) and d approach 3 (changed PEGda concentration cryogels. Porosity was measured by mercury intrusion porosimetry and elasticity by compressive strength test. The experiments were done in triplicate. Error bars represent standard faults
