  • %X "Smart" coatings capable of both detecting and actively eliminating hazardous agents are being investigated as new ways for combating chemical and biological contamination. Specifically, we took advantage of the unique surface properties of carbon nanotubes (e.g. high surface area, controllable morphology and size etc.) to immobilize a cocktail of enzymes and subsequently we incorporated the enzyme-carbon nanotube conjugates into latex-based paint. Operational properties of the enzymes were optimized to yield high loading and activity on the nanotube support, and long-term operational stability in the composite. This "green" namely enzyme-based technology, eliminates the risks associated with chemical decontamination that uses corrosive agents and generates substantial amounts of residual waste. Moreover, the "green"-based composites developed herein are cost-effective and decontaminate on contact without imposing logistical burden to the personnel.
