AC electrothermal flow (ACEF) is the fluid motion created as a result of Joule heating induced temperature gradients. ACEF is capable of performing major microfluidic operations, such as pumping, mixing, concentration, separation and assay enhancement, and is effective in biological samples with a wide range of electrical conductivity. Here, we report long-range fluid motion induced by ACEF, which...
This study reports a hybrid electrokinetic microdevice for rapid concentration and detection of circulating cell-free (cf)DNA. Rapid molecular analysis of cfDNA has the potential to change the current practice of medicine, such as in cancer diagnostics and in monitoring the efficacy of cancer treatments. With a combination of AC electrothermal flow and dielectrophoresis, the hybrid electrokinetic...
