MATERIALS ANALYSIS


Understanding the materials science of medical devices on a molecular scale contributes to a better understanding of their interaction with the human body and aids future developments in form and function. Mark Turner of Medical Engineering Technologies summarises some of the techniques employed in chemical analysis, particularly of surfaces.


’ve got a great idea! What we really need is a urethral catheter that slides so smoothly you can’t even feel it. It should be totally resistant to bacterial growth, very, very flexible and of course it won’t kink. Or maybe we should develop an artificial hip in a material that is so well integrated into the body, that a year after the operation, it is indistinguishable from

real bone. Ideas are great, but what is really involved in getting these great ideas into service? Good materials analysis will certainly help them along the way. Here we look at some of the analyses used in functional and biocompatibility testing.


Medical devices depend on their physical, chemical and surface properties to deliver their actions and deliver
