Scientists at Georgia Tech have developed a potential new treatment against cancer that attaches magnetic nanoparticles to cancer cells, allowing them to be captured and carried out of the body. The novel therapeutic approach, which has been tested in the laboratory and will now be looked at in survival studies, was detailed online on July 9th in the Journal of the American Chemical Society.

During this week’s GEN podcast, Dr. John McDonald, one of the paper’s authors, talks about how the idea for this method of treating cancer came about and developed. He discusses which types of cancer are more amenable to this therapy and provides the details on the actual experiment that was carried out in mice. Dr. McDonald points out the importance of using a small peptide to modify the nanoparticle to target it directly to the tumor cells and offers suggestions on how this technology be packaged to make it a feasible cancer cell removal system for human applications.
