Biomaterials are those materials which (synthetic and natural; solid and sometimes liquid) that are used in contact with biological systems or in medical devices. As a field Biomaterials has seen continuous growth for nearly five decades and utilizes various methods from materials science and engineering, chemistry, medicine, biology. Biomaterials also considers ethics, law and the health care delivery system. Mainly biomaterials are used for medical purposes, but they can also be useful in the sector of growing cells in culture, to assay for blood proteins in the clinical laboratory, in processing biomolecules in biotechnology, for fertility regulation implants in cattle, in diagnostic gene arrays, in the aquaculture of oysters and for investigational cell-silicon "biochips." The commonality of these applications is the interaction between biological systems and synthetic or modified natural materials.
Biomaterials are infrequently utilized all alone yet are all the more usually coordinated into gadgets or implants. Subsequently, the subject can't be investigated without considering biomedical devices and the biological response to them. Biomaterials are once in a while utilized all alone however are all the more generally incorporated into implants and devices. In this way, the subject can't be investigated without considering biomedical device and response to them.
