Stem Cell and Biomaterials

Advanced Materials

Biomaterials are substances which interact and react with the biological system either as a part of the medical device or as a part to replace or repair any damaged organs or tissues. Biomaterials can be derived either naturally or synthetically. Natural Biomaterials are silk, gelatin, etc. while the Synthetic ones are the various polymers. Bioceramics like Alumina, Bioglass, Zirconia are used to repair damaged portions of the musculoskeletal system and also used in dental and orthopaedic fields. Biocomposites are formed by using resin and natural fibres. It can be non-wood natural fibres (rice, wheat, coconut, etc.) or wood fibres (magazines, soft and hardwoods). Metals are mainly a choice of biomaterials in fields of dental, orthopaedic, cardiac implants. As metals can lead to wear, corrosion, so surface coating and modification of metals are necessary for medical applications.
