A group of researchers at Rice university and Virginia Tech have collaborated to create Multi-walled carbon nanotubes (MWCNTs). These MWCNTs comprise many carbon nanotubes nestled inside one another. The MWCNTs are injected into kidney tumors in mice. The nanotubes are then exposed to 30 seconds of 3W near-infrared laser irradiation. This incident radiation causes the nanotubes to vibrate creating heat. This heat was found to be enough to shrink tumors, with results as high as 80% of tumors disappearing.
The researchers are now investigating the toxicology of this treatment and moving on to larger animal trials. The hope would be to translate this treatment into humans. – CT
