A Biosensor for Early Detection of Ovarian Cancer

Iranian Researchers at Kurdistan University recently design a biosensor which can diagnose the ovarian cancer in early stages by using blood samples.

Ovarian cancer is one of the deadliest cancers among women because it is not easy to diagnose and common detection modalities are not entirely reliable.
“In this research project we tried to develop a method to detect and measure ovarian cancer anti-genes with a highly sensitive aptasensor in the presence of other similar anti-genes. This aptasensor is made of reduced graphene oxide nanolayers coated on a flexible polymethyl methacrylate polymer film” said Dr. Abdoolah Salimi a member of the research team. The aptasensor helps diagnose the ovarian cancer quicker and with a higher accuracy than current clinically available techniques.
To increase the surface area and sensitivity of the sensor, in this approach carbon nanotubes are used. Also, reduced nanolayers of graphene oxide behave as field-effect transistor channels which makes the small scale design possible. This method can produce portable micro analyzer systems which can measure anti-gene in infected area without any need for a biopsy.
Dr. Abdoolah Salimi, a faculty member at Kurdistan University and Dr. Samira Majd, Ph.D. graduate from Kurdistan University are two senior researchers who have conducted this research. The results of this research have been now published in a special issue in the journal of Analytica Chimica Acta. (article link)
