Abstract

The present disclosure provides a microfluidic device comprising a set of micro-structured electrodes. The electrodes are made of a fusible alloy such as Field's Metal and are patterned on a layer of PDMS. The molten fusible alloy is poured over the patterned PDMA layer and a suction force is applied to ensure uniformity of flow of the molten metal. A second layer comprising a flow channel orthogonal to the direction of the micro-structured electrodes is disposed under the first layer to form the microfluidic device. The device shows enhanced sensitivity to RBC detection at high frequencies that are also bio-compatible (above 2 MHz). Multiple layers of the micro-structures electrodes can be sandwiched between layers of flow channels to provide a 3D microfluidic device.
