Dear All, I do not know if it is absurd of me to address this issue some 6 months after it is being posted. But anyway, I am rather confused by the profilerated use of the term biocompatible. As far as I know, bicompatible means the characteristic of being able to fuse with the body tissues (bones etc) rather then being inert as the term bio inert is supposed to mean. One example of biocompatible material is HA, a ceramic that is widely used in the biomedical field for re-construction. It is able to fuse with the human bones without rejection or encapsulation. However, I guessed materials like glass and silicone rubber is more of bio inert then of bio compatible. It would be fine if the two terms are used interchangeably for devices not involving implants, but will be of grave consequences if it does. I do look forward to any form of clarification for that matter.
