Abstract
A method of determining whether a substrate has been subjected to an energy source. In one embodiment, the method includes the steps of providing a polymeric surface, providing a light emitting material having a specified emission spectrum that changes upon exposure to an energy source on the surface or embedded in said substrate and applying said energy source to said surface with said light emitting material. This method can be particularly useful for detecting the bond quality in medical devices.
