The ability to rapidly detect cell free circulating (cfc) DNA biomarkers and drug delivery nanoparticles directly in blood is a major challenge for early disease detection and nanomedicine. We now show that a microarray dielectrophoretic (DEP) device can be used to rapidly isolate and detect high molecular weight (hmw) DNA nanoparticulates and nanoparticles directly from whole blood. At DEP frequencies...
The ability to effectively detect disease‐related DNA biomarkers and drug delivery nanoparticles directly in blood is a major challenge for viable diagnostics and therapy monitoring. A DEP method has been developed which allows the rapid isolation, concentration and detection of DNA and nanoparticles directly from human and rat whole blood. Using a microarray device operating at 20 V peak‐to‐peak...
In biomedical research and clinical diagnostics, it is a major challenge to measure disease‐related degradative enzyme activity directly in whole blood. Present techniques for assaying degradative enzyme activity require sample preparation, which makes the assays time‐consuming and costly. This study now describes a simple and rapid electrophoretic method that allows detection of degradative enzyme...
