Abstract: A method for collecting a compound from a surface, the method comprising providing a silicone adhesive collector comprising a silicone adhesive layer on a backing; contacting the silicone adhesives collector and a first solvent to provide a wetted collector; contacting the silicone adhesive layer of the silicone adhesive collector and a surface to be analyzed to provide a loaded collector; and removing the loaded collector from the surface to collect the compound. The disclosure also relates to a system for collecting a chemical compound from surfaces, the system comprising a silicone adhesive collector comprising a backing, and a silicone adhesive layer disposed on the backing; a first solvent; and instructions to dispose the first solvent on the silicone adhesive collector, the surface, or a combination thereof.

Abstract: The present invention provides compositions effective in decontaminating either biological pathogens or both chemical and biological pathogens. These compositions are particularly suitable for the decontamination of biological warfare agents or both chemical and biological warfare agents The compositions comprise generally a blend of biocides, and may additionally comprise a protein and an enzyme. Further, the composition is contained in a buffered foam forming material for ease in distribution The compositions are nontoxic, noncorrosive and nonflammable.

Abstract: An optical disc having machine-readable, information-encoding features is provided with a barrier layer secured to the disc. This barrier layer is configured to prevent machine-reading of the features. A reading-inhibit agent, included in the disc and activated by removal of the barrier layer, is operative, once activated, to alter the disc to inhibit reading of the disc. Alternately, the barrier layer can be eliminated, and the reading-inhibit agent can be activated by initial reading of the disc, as for example by exposure to optical radiation associated with reading of the disc, or rotation of the disc.

This barrier layer is configured to prevent machine-reading of the features. A reading-inhibit agent, included in the disc and activated by removal of the barrier layer, is operative, once activated, to alter the disc to inhibit reading of the disc, after some period of time. Alternately, the barrier layer can be eliminated, and the reading-inhibit agent can be activated by initial reading of the disc, as for example by exposure to optical radiation associated with reading of the disc, or rotation of the disc.
