Pete - here is the con't...
That’s right. And how long that would last would in large part depend on how it’s attached to the surface. Is it attached to the surface of, for example a catheter, an IV tube? Or, is it mixed in throughout the plastic, so that even if the surface wears away there’s still a polymer in there. And part of it also would depend on what is this material exposed to? Plus, self sterilizing doesn’t mean self cleaning. So, if the surface got covered over, whether it’s with mud or dirt or something like that, the surface is covered up. The surface wouldn’t be available to interact with bacteria. So, it would have to be cleaned and renewed somehow. But, in our experiments, we’ve shown that when we add polymers to these types of plastics and coatings, in fact is long lasting. It does withstand repeated exposure to bacteria and keeps on killing. We can even store these materials in water for many weeks, and it keeps their activity. So, it doesn’t dissolve out of the material.
