Scientists from Florida and Canada have teamed up to develop a new tool for watching how cancer drugs affect their targets. The researchers linked drugs to tiny structures known as quantum dots (Qdots). When the drug-Qdot combination enters the cancer cells, the Qdots give off a reddish color, allowing them to be easily detected. The research should speed up the testing of new cancer drugs and allow tracking of drug activity over time.
