Modification of bacterial cellulose with micro-structured gelatin coating

We develop simple procedure for modification of bacterial cellulose with micro structured gelatin coating. New technology includes preparation of microstructured gelatin coating onto bacterial cellulose membrane. It is post-synthetic modification of bacterial cellulose. Procedure involves: i) pouring the gelatin-water solution containing carbodiimide cross-linkers (EDC/NHS) onto the bacterial cellulose, ii) immediate freezing onto freezing plate, iii) slow thawing (within fridge, 8°C), and iii) final washing. Resulting membranes (photo) are highly flexible, and both layers are tightly integrated.
