 Linked or dried DNA is usually better off than nucleic acids in solution
when UV irradiation, but here the aim is to break down also such 
material...

 This is a more targeted question about the general theme of which 
reagents we use in our bench work might be wrecked by this technology...
(e.g., can this affect autoradiographic films, (charged) membranes, etc.)

 Anybody heard/learned anything specific about this aspect?

Greetings,
 Roland
