Porous Chitosan

In this study, layer structured porous chitosan scaffold was successfully fabricated using thermal induced phase separation method. The scaffold had a layer structure with interconnective pores (50- 300 μm) and high porosity (>90%) using citric or acetic acid as the solvent. However, the results of compressive modulus of the scaffold showed that acetic acid was a better choice, and the compressive modulus of scaffold increased with chitosan concentration in acetic acid. The scaffold is very promising for tissue engineering.

Porous Chitosan

The chitosan scaffold we prepared have a high porosity of about 90% with pore sizes from 50 to 200m. Lactose was conjugated onto the inner surface of the highly porous chitosan scaffold. It was used as substrate for rat hepatocytes culture. The cell attachment ratio was much higher than on monolayer membrane and non-modified porous scaffold. Metabolic activities of the cells were evaluated in terms of albumin secretion and urea synthesis. It was found that hepatocytes cultured on the modified scaffolds showed an increase in albumin secretion during the first 4 days and were more stable than that on non-modified scaffold. The results showed that the microstructure of porous scaffolds provides large surface for cells to adhere and facilitates nutrient and oxygen transportation. Such lactose modified scaffold has a potential application in bioartificial liver support system.

Proper Material

Artificial photosynthesis is a new method to generate sustainable energy. In order to constrain reaction solution in a solid state structure and increase the reaction efficiency, we designed a novel artificial photosynthesis device with porous chitosan scaffold with interconnected micro-channels. We built 3D interconnected chitosan channels with a home-made heterogeneous 3D rapid prototyping machine, and we used lyophilization method to generate the nano pores inside the chitosan scaffold. Chitosan gel in acetic acid can form different viscosities by different chitosan’s molecular weight and the different concentrations of both chitosan and the acetic acid, so we found a proper material recipe to construct 3D scaffold by our own rapid prototyping machine. Optional support material sodium bicarbonate is used in printing 3D scaffold for holding the printed structure permanently, and the result shows that this method can make the scaffold stronger and harmless to further processes such as adding light reaction units and dark reaction solution into the device.
