Bio-nanotechnology to kill cancer cells

Carbon nanotubes have already found applications in engineering but so far any biological application has been hampered by their poor interaction with biological systems.

The Surrey team has overcome this problem by wrapping DNA and RNA around carbon nanotubes making them biocompatible. The aim of the project is to attach additional molecules to the RNA-wrapped carbon nanotubes to target them towards cancer cells. In combination with laser treatment the carbon nanotubes may then be used to kill the cancer cells.

Although there is still a long way to go before any new drugs based on this technology are developed, the scientists hope that their work will eventually lead to more effective treatments for cancer.

The multidisciplinary project involves biologists, engineers and physicists from the University of Dresden in Germany, the University of Toulouse, France, the University of Linz, Austria, the University of Twente, The Netherlands and the University of Surrey.
