METHOD FOR THE EVALUATION OF IMPLANTABLE MATERIALS

摘要

A method for evaluating whether a material will allow bacteria to pass throu gh the material comprising providing bacteria which are modified to produce a first detectable signal, placing the bacteria on a first side of the materia l being evaluated, and determining whether the first signal is present on a second side of the material. A method for the evaluation of a material to determine whether the material is susceptible to bacterial contamination or colonization comprising providing bacteria which are modified to produce a first detectable signal, exposing the material being evaluated to the bacter ia and determining whether the first signal is present on the material.
