Abstract:
When facilities, equipment, vehicles, and other objects are threatened with contamination by chemical warfare agents (CWAs), whether in combat or terrorism situations, threat mitigation can be accomplished by reactive nanoparticles, applied before or after attack. NanoScale® Corporation has developed proprietary sorbents that been demonstrated to be effective for destructive adsorption of CWAs (including chemical mustard and nerve agents such as soman and VX) and a broad range of acids and toxic industrial chemicals that could be used in battlefield and/or terrorist attacks. These sorbents have been shown to convert these hazardous compounds into much less toxic, frequently nontoxic, compounds. Additionally, several formulations of modified reactive nanoparticles have been found to be effective for destruction of biological warfare agents such as Bacillus anthracis (anthrax) spores and plague bacteria. NanoScale is developing means of applying its powdered decontaminants in a variety of methods tailored to a range of situations, such pressurized cylinders, hand-held wipes, shakers, protective textiles, and an adherent form for spraying onto surfaces such as walls and ceilings. These systems can be used in a broad range of situations, such as contamination prevention or decontamination.
