Coding with DNA

Guest: Rebecca Chen, Graduate Student in Chemical and Biomolecular Engineering, University of Delaware One major problem with chemotherapy is that to kill the cancer cells, the treatment also kills lots of healthy cells, too.  Radiation is used to treat cancer in a localized area in the body. But wouldn’t it be so much better if the drug could float harmlessly in the body until it sensed a cancer cell and only then would it turn toxic? University of Delaware chemists are one step closer to making that a reality.
