[Progress in the studies on the evaluation of biocompatibility of biomaterials].

Biocompatibility remains the central theme for biomaterials applications in medicine. It generally refers to the compatibility between the biomaterials and the receptor, including tissue-compatibility and blood-compatibility. The definition of the biocompatibility has been greatly changed in recent years; it is now accepted as involving two principle areas, one is the principle of 'biosafety', the second is the principle of 'biofunctionality'.
