The electrochemical encapsulation process involves assembling of collagen along with Nano/bio materials using an isoelectric focusing mechanism. We have showed that a wide range of Nanomaterials such as carbon nanotubes, polymeric nanoparticles, magnetic calcium phosphate nanoparticles?and biomolecules can be encapsulated into collagen. These novel collagen-based composite materials possess improved electric, mechanical, antimicrobial, magnetic, bioactive properties. Thus, this novel electrochemical encapsulation process offers a means to fabricate novel biomaterials for various biomedical applications such as tendon/ligament, nerve, skin tissue engineering, tendon/ligament to bone grafts, and sutures, etc.展开更多

The resultant material has a clear biomimetic structure like bamboo and wood. The skin region is enriched with oriented high-strength thermotropic liquid crystal polymer fibrils, while the core region with polystyrene (PS) micro-cells. The diameter and density of micro-cells can be controlled by the processing parameters such as temperature and pressure. And the skin thickness can be controlled conveniently by varying the composition of polystyrene and liquid crystal polymer.展开更多
