Clemson University chemist Ya-Ping Sun and his research team have developed such a countermeasure strategy to weaponized anthrax, a biological agent used by a terrorist or terrorists that killed five Americans in 2001. The Clemson team’s findings are published online in the “Journal of the American Chemical Society.”
“For anthrax to be effective, it has to be made into a fine powder that can easily enter the lungs when inhaled. That is what makes it lethal,” said Sun. “What we have done is come up with an agent that clings to the anthrax spores to make their inhalation into the lungs difficult.”
Anthrax spores are covered with carbohydrates, or simple sugars, that are used to communicate with or attract other biological species. The Clemson team used carbon nanotubes as a platform or scaffolding for displaying sugar molecules that would attract the anthrax spores. Carbon nanotubes are hollow tubes made of carbon atoms. Typically one-hundred thousandth the thickness of a single human hair, nanotubes are formed from intensely heated carbon. When sugar coated, the carbon nanotubes bind with the anthrax spores, creating clusters that are too large to be inhaled –– stopping their infection and destruction.
Sun said a similar approach using sugar-coated carbon nanotubes to stop the spread of E. coli bacteria was tested successfully in 2004. He sees this new method potentially as a way for first responders to contain anthrax in an office or mailroom setting using a water-based gel, foam or aerosol spray, and he thinks it has potential application on the battlefield in larger quantities.
With Sun on the Clemson research team were Haifang Wang, who visited from Peking University in Beijing, China; Lingrong Gu, Yi Lin, Fushen Lu, Mohammed J. Meziani, Pengju G. Luo, Wei Wang and Li Cao.
The National Science Foundation and the United States Department of Agriculture funded the study.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
