Oak Ridge Researchers Optimistic About Nanohorns
A team of scientists from the Oak Ridge National Laboratory and the University of Tennessee have been seeing promising results during their testing of single-walled carbon nanohorns.
Nanohorns are specially engineered nanoparticles designed to facilitate targeted drug delivery. In addition to their possible medical uses, the tiny devices have been shown to have potential commercial energy and fuel cell applications.
Unlike previous studies conducted on nanotube structures, which documented adverse biological responses, the cone-tipped nanohorns caused no pulmonary toxicity issues or inflammatory reactions. The researchers believe carbon nanohorns could find large-scale applications sooner than nanotubes because they don’t appear to pose any health hazards and they are easier to produce.
A report on the nanohorn research is being published in an upcoming edition of the journal Nanotoxicology.
