DEP is a cost-effective technique for manipulating biological particles in microfluidics. This study presents an advanced solution strategy for focusing and separating cancerous cells, with theoretical calculations and a simulation model determining optimal parameters. The proposed method shows potential as a simple, low-cost approach to enhance cancer detection at early stages.
Dielectrophoresis (DEP) is known as an attractive and frugal technique to manipulate biological particles in microfluidics. This study presents the advanced solution strategy of a DEP-based microfluidic channel for focusing and separating cancerous cells in continuous flow. Theoretical calculations were carried out to define the favorable parameters in the electric field operation of the microchip. A simulation model was also used to explore the performance of the design in the isolation of circulating tumor cells (CTCs). It revealed that the optimal conditions of the device are suitable to effectively separate CTCs from red blood cells (RBCs) within the channel structure, with a high flow rate of 1.5 mu L/min, and an electric amplitude as low as 10 V-pp, at the frequency of 1 kHz. The proposed method has shown potential as a simple, easy-to-operate, and low-cost approach enable to enhance the diagnosis systems for cancer detection at early stages.
