Quantum dots used for cancer tests
Abstract:
Researchers at Johns Hopkins U. have developed a test for early-warning cancer signs using quantum dots, with potentially "huge clinical implications."
The system, which detects both the presence and quantity of certain DNA markers in the sputum of lung cancer patients, and was found to be more sensitive and faster than conventional methods. More real-world testing is needed, but "if we continue to see exciting progress, this testing method could easily be in wide use within the next five years," according to study co-author Stephen B. Baylin, deputy director of the Johns Hopkins Kimmel Cancer Center.
