RESUMO
From a concrete example, the authors remind the interest to envisage the possibilities of sterilization as early as the initial period of a research about biomaterials. Indeed certain kinds of sterilization may be too much aggressive for biomaterials, especially the polymers, whom the structure is so impaired. These biomaterials may become ineffective even dangerous and blight a long time of research. The authors also expose the necessity to respect the good manufacturing practices of laboratory and the rules of hospital hygienics which is indispensable for all the members of the teams which participate to biomedical or clinical researches. A condition for the respect of these rules is the utilization of a common and well understood language between the medical and no medical teams.
