These structures are designed to “mimic” some type of biological process which can also interact with a biological mechanism. One of the main focuses of this research is in the area of human repair and idea of self-assembly. This is also called “tissue engineering”. The biostructures will be inserted into the body to form a template to assist the body. Using the bone example again, the biostructure will form an outer shell around the area that needs to be repaired. The natural bone can then grow around the structure like a rose grows over a trellis. So now we don’t have to replace the bone we can simply, repair the damage easily. Tissue engineering might replace today’s conventional treatments like organ transplants or artificial implants.
