Biocompatibility
In earlier definitions of material and organism biocompatibility was equated
with inertia. The so-called no-definition contains demands from the biomaterials
like, for example, no changes in the surrounding
tissue and no thrombogenic, allergenic, carcinogenic and toxic reactions [9]. Yet a concept
of inertia is questionable as there is no material that does not interact with the body;
in the case of “inertia” of a biomaterial there is only a tolerance of the organism [10].
As a result of this insight Williams defined biocompatibility as “the ability of
a material to perform with an appropriate host response in a specific application”.
In Ratner's latest definition biocompatibility
even means the body's acceptance of the material, i.e. the ability of
an implant surface to interact with cells and liquids of the biological system and to cause exactly
the reactions which the analogous body tissue would bring about [2]. This definition requires
knowledge of the processes between the biomaterial's surface and the biological system.
Presents three papers on Biomedical Applications/ Polymer Blends; Polymers for Biomedical, Applications; Improvement of the Interface Compatability, and Poly (E-Caprolactone) Blends.
