Abstract: A heat-shrinkable anti-fomitic device in the form of a bag or tube forms a cover for an object which prevents cross-infection by bacteria and other pathogens that may reside on the object. The heat-shrinkable anti-fomitic device can have a sterile interior that is sealed or stored flat during manufacture to maintain sterility.

The method and apparatus are useful in the fabrication of biotechnologically functional devices, Bio-MEMS devices, and in the fabrication of microfluidic devices for biological applications.
