Johns Hopkins University (JHU) researchers have developed a highly sensitive test that searches for DNA attachments that often serve as early warning signs of cancer. The new technology uses tiny crystals called quantum dots to detect the presence and quantity of certain DNA changes. It could be used to detect people at risk for developing cancer and let doctors know the effectiveness of a particular cancer treatment.
Published in the August issue of the journal Genome Research, the test was developed by Jeff Tza-Huei Wang, an associate professor of mechanical engineering and colleagues at the Johns Hopkins Kimmel Center.
"If it leads to early detection of cancer, this test could have huge clinical implications," said Jeff Tza-Huei Wang, an associate professor of mechanical engineering whose lab team played a leading role in developing the technique. "Doctors usually have the greatest success in fighting cancer if they can treat it in its early stage."
