Biocompatibility (or tissue compatibility) describes the ability of a material to perform with an appropriate host response when applied as intended. A biocompatible material may not be completely "inert"; in fact, the appropriateness of the host response is decisive. [15]
Medical grade silicones are silicones tested for biocompatibility and are appropriate to be used for medical applications. [1] In the United States, the Food and Drug Administration (FDA) Center for Devices and Radiological Health (CDRH) regulates devices implanted into the body.
The primary role of many of these polymers was to act as a biocompatible cement in the fixation of prostheses and in the replacement of joints. Newer biologically compatible synthetic and natural biodegradable polymers have been developed; these include polyglycolide, polylactide, polyhydroxobutyrate, chitosan , hyaluronic acid , and hydrogels .
Because of its mechanical structure, collagen has high tensile strength and is a non-toxic, easily absorbable, biodegradable, and biocompatible material. Therefore, it has been used for many medical applications such as in treatment for tissue infection, drug delivery systems, and gene therapy.
The ISO 10993 set entails a series of standards for evaluating the biocompatibility of medical devices to manage biological risk. These documents were preceded by the Tripartite agreement and is a part of the international harmonisation of the safe use evaluation of medical devices. [1]
A hip implant is an example of an application of biomaterials. A biomaterial is a substance that has been engineered to 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.
Nitinol biocompatibility is an important factor in biomedical applications.Nitinol (NiTi), which is formed by alloying nickel and titanium (~ 50% Ni), is a shape-memory alloy with superelastic properties more similar to that of bone, [clarification needed] when compared to stainless steel, another commonly used biomaterial.
Additionally, they must be biocompatible, meaning that they do not cause any adverse effects to cells. [37] Silicone, for example, is a synthetic, non-biodegradable material commonly used as a drug delivery material, [38] [39] while gelatin is a biodegradable, natural material commonly used in cell-culture scaffolds [40] [41] [42]
