A medical implant according to the present invention includes a substrate having a first plurality of openings and a second plurality of openings formed therein. The chemical compounds are stains that become fluorescent upon illumination and interaction with double stranded DNA, but exhibit reduced or no fluorescence in the absence of double stranded DNA. The container defines a second wall of plastic in which the container has a freezable layer of blue gel that is sealed between the first and second walls of plastic and the freezable layer is made of freezable material such as \u201cBlue Ice\u201d which enhances the chilling of the food products supported in the volume. A release layer can be applied onto at least a portion of one or more sides of the structure.
