Abstract

The ability to rapidly detect cell free circulating (cfc) DNA and other nanoparticulate disease biomarkers directly in blood is a major challenge for nanomedicine. We now show that AC Electrokinetic (ACE) microelectrode array devices can be used to rapidly isolate and detect cfc-DNA nanoparticulates directly from whole blood and other high conductance samples (plasma, serum etc.). The device shows isolation of naked DNA in water and plasma at >500bp size and can isolate DNA down to 50 picograms in 50uL of fluid. Disease specific cfc-DNA materials could also be detected directly in blood from patients with Chronic Lymphocytic Leukemia.
