Cancer nano-eliminators

Cancer nano-eliminators

According to American researchers, carbon nanotubes can facilitate the use of Raman spectroscopy as a technique for detection, real-time monitoring and even, with the help of a laser, the elimination of cancer cells.

The discovery could open a new battlefront in the fight against cancer with the promise of a new generation of therapeutic agents beyond surgery, radiation and conventional chemotherapy drugs.

Alex Biris of the University of Arkansas at Little Rock (UALR) is chief scientist at the Center for Nanotechnology and is working with his medical science colleague Vladimir Zharov on developing the technique. The researchers have reported the details of their initiative in the latest issue of the Journal of Biomedical Optics.

"Until now, no one has been able to fully understand and study in real time how these nanoparticles travel through a living system," Biris said. “Using Raman spectroscopy, we have shown that it is possible not only to monitor and detect nanomaterials moving through the circulation, but also to detect individual cancer cells labeled with carbon nanotubes. in this sense, we can measure its clearance index and biodistribution kinetics through the blood and lymphatic systems ”.
