Preparation of bi-continuous macroporous polyamide copolymer membranes for cell culture

▸ Polyamide copolymer membranes are prepared by nonsolvent induced phase separation. ▸ High molecular weight chitosan has been employed as the pore former. ▸ Membranes exhibit uniform bi-continuous structure. ▸ Membranes have large pore size and high porosity. ▸ L929 cell can grow inside the membrane.
