Biodegradable Biomaterials are those which are intended to get degraded in the body safely. These materials are either magnesium based or iron based alloys. They are mainly applied for cardiovascular implants as stents and orthopaedics. Hydrogels are the polymeric materials containing water, which are the first biomaterials for human use. Nanofiber scaffolds are used for orthopaedic tissue repair and regeneration. Biomimetic materials are those which can show cellular responses mediated by scaffold and peptide interactions from extracellular matrix.
