Narrator: This is Science Today. A team of physicists from the University of California , Berkeley and the U.S. Department of Energy's Lawrence Berkeley National Laboratory have built the world's smallest radio from a single carbon nanotube. Cenzan Ozkan, a professor of chemical engineering at the University of California, Riverside also works with carbon nanotubes and says the potential in this field is enormous.

Ozkan: First of all, it's a very exciting field, very interesting, as you conduct more and more work, you get more enthusiastic and you get more motivated. At the same time, there is just - especially within the last several years - a large number of people have entered this field and that has opened up many possibilities of collaboration.

Narrator: Ozkan's lab is currently partnering with one of the cancer nanotechnology centers that is led by the University of California, San Diego.

Ozkan: There is a lot of research that is going on in this field. That includes the employment of nanoparticles, carbon nanotubes, engineered nanoplatforms that can serve as drug therapeutics.
