Document Summary
), including both natural and synthetic, refer to any substance that is intended to. Biomaterials interact with biological systems for a medical purpose - either a therapeutic (treat, augment, repair, or replace a tissue function of the body) or a diagnostic one defined by application not chemical makeup. Assist in healing: sutures, bone plates, screws. : derived from biological source remodeling as compared to synthetic biomaterials. Advantages : availability, ecological safety, increased biocompatibility, biodegradability, and. Disadvantages : limited physical and mechanical stability (may not be suitable for load bearing. Protein origin biomaterials created using stem cell differentiation and transplantation, provide applications) structure to tissues. Secreted by worms, advantages : [low degradation rate, superior handling characteristics], disadvantages : [inflammation, reaction can lead to encapsulation]; collagen . Polysaccharides origin biomaterials usually derived from agricultural feedstock or crustacean shell wastes, extremely bioactive, sugar monomers help maintain extracellular matrix. Hyaluronan through encapsulation of islet cells, controlled local drug release]; agarose .
