Abstract: A method for separating charged particles in a liquid sample is disclosed. The method includes the steps of driving the liquid sample containing a plurality of charged particles to flow, forming a non-uniform electric field in the direction relative to the flow direction of the liquid sample by two electrodes, and aggregating the charged particles under the non-uniform electric field so as to separating the charged particles from the liquid sample. When the liquid sample flows through the non-uniform electric field, it doesn't contact to the electrodes. A device and its manufacturing method for separating charged particles in a liquid sample are also disclosed. Accordingly, the charged particles can be separated from the liquid sample easily and more effectively.

Abstract: In a biomedical chip for blood coagulation tests and its manufacturing method and use, the biomedical chip comprises a substrate layer, a middle layer, and a cap layer, engaged and stacked with each other to define a microfluidic channel which has a first inlet and an outlet of the microfluidic channel respectively. A mixing interval is expanded outward from the microfluidic channel and interconnected to a second inlet, and has an interconnect portion and a capillary portion disposed between the substrate layer and the cap layer, and more specifically disposed around the periphery of the interconnect portion. With the biomedical chip having the substrate layer and cap layer made of a hydrophilic material, the blood and the reagent can be driven automatically by the capillary force of the microfluidic channel to flow and mix with each other, and the hydrophilic capillary force can be permanently maintained.
