Abstract:
A researcher affiliated with Johns Hopkins Institute for NanoBioTechnology has developed a highly sensitive test using quantum dots to detect external chemical modifications to DNA called methylations. Alterations to DNA that do not involve a change in the genetic code, yet can influence gene expression, fall into the emerging science of epigenetics.
The nanotechnology based test for epigenetic markers could be used as an early detection method for cancer or to determine whether a particular cancer treatments is working or not. The research was performed by INBT affiliated faculty member Jeff Tza-Huei Wang, an associate professor of mechanical engineering from the Whiting School of Engineering, and Stephen Baylin, deputy director of the Johns Hopkins Kimmel Cancer Center. Their findings were published in the August 2009 issue of Genome Research.
