Today, one of the limitations associated with cartilage grafting is the lack of bonding between the implanted materials and the natural tissue. Helical rosette nanotubes (HRNs) are novel biomimetic self-assembled supramolecular structures whose basic building blocks are DNA base-pairs, which can solidify into a viscous gel at body temperatures in short periods of time. HRNs are similar in size to...
This research work started with the development of a robotic system that mimics the process of spider web formation. The robotic system is able to convert small samples of biopolymer or synthetic polymer solution into 3D patterned non-woven structure. Fiber obtained from this system varies from sub micron diameter to 25 micron diameter depending upon the spinning process (dry spinning or wet spinning)...
The national organ transplant waiting list is growing five times faster than the rate of organ donation, indicating a need to provide a more plentiful source of tissue replacements. Furthermore, the national number one cause for human death is heart disease. Because of the high percentage of heart failure and a low number of successful organ donations, studies are now focusing on the design of new...
