- Biocompatible material
In
surgery , a biocompatible material (sometimes shortened to biomaterial) is a synthetic or natural material used to replace part of a living system or to function in intimate contact with living tissue. Biocompatible materials are intended to interface with biological systems to evaluate, treat, augment or replace any tissue, organ or function of the body. Biomaterials are usually non-viable, but may also be viable.A biocompatible material is different from a biological material such as
bone that is produced by abiological system .Artificial hip s,vascular stent s,artificial pacemaker s, andcatheter s are all made from different biomaterials and comprise differentmedical devices .Biomimetic materials are not made by living organisms but have compositions and properties similar to those made by living organisms. The calciumhydroxylapatite coating found on many artificial hips is used as abone replacement that allows for easier attachment of the implant to theliving bone .Surface functionalization may provide a way to transform a bio-inert material into abiomimetic or evenbioactive material by coupling ofprotein layers to thesurface , or coating the surface with self-assembling peptide scaffolds to lendbioactivity and/or cell attachment 3-D matrix.Different approaches to functionalization of biomaterials exist.
Plasma processing has been successfully applied to chemically inert materials likepolymer s orsilicon to graft variousfunctional group s to thesurface of the implant.Polyanhydrides are polymers successfully used as a drug delivery materials.ee also
