Natural Material

Description: Biomaterials can be classified into two main groups: synthetic and natural biomaterials. The latter exhibit several advantages over the former, such as biocompatibility, inherent biodegradability, remodeling and critical biological functions. Therefore, natural biomaterials are usually applied in the repair or replacement of damaged human tissues and organs. They have the ability to adequately support cell adhesion, migration, proliferation and differentiation. For example, natural polymers have been used to make natural hydrogels as extracellular matrix that mimic the biological milieu to bridge the gap between conventional cell cultures and complex native in vivo environments. Cellulose, a polysaccharide mainly found in plants can promote bone regeneration. Another example is the silk fiber produced by spiders, its biodegradability is ideal for applications like surgical suture and drug delivery.
