IBN scientists harness ultrasmall peptides to repair spinal disc damage

New ultrasmall peptides that can be used as building blocks for a wide range of regenerative applications such as spinal disc replacement and cartilage repair have been developed by scientists at the Institute of Bioengineering and Nanotechnology (IBN), the world's first bioengineering and nanotechnology research institute. These peptides spontaneously assemble in water to form hydrogels, which resemble collagen, a major component of connective tissues found in cartilage, ligaments, tendons, bone and skin.
