PROBLEM TO BE SOLVED: To provide biopolymers and biocomposite materials and structures, and methods of making and using them.SOLUTION: Oriented collagen based biocomposite materials and structures, and methods of making the are provided. There is provided a method of producing a fibrillar biopolymer pseudo-fiber from a thin ribbon of an oriented fibrillar biopolymer material, the method comprising the steps of: dipping the ribbon into a solution; and pulling the oriented biopolymer material from the solution in such a way that the material autonomously collapses into a pseudo-fiber at the air-liquid interface. The fibrillar biopolymer pseudo-fiber is also provided which is formed for use as an in vivo cell guiding scaffold. The fibrillar biopolymer pseudo-fiber or is pseudo-fiber is further provided which is formed to deliver live cells for tissue repair and regeneration and components of platelet rich plasma. |
