Separation of Circulating Tumor Cells ( CTCs) from the bloodstream for the treatment of blood cancer and the prevention of spread of Malignant tumor cells to other organs without causing damage to healthy cells is a major challenge in the field of Cancer treatment. Similarly, isolation of Tumor Cells from an infected blood sample for an early diagnosis requires the expertise of a skilled researcher and the use of expensive reagents which limits its affordability.
The current project focuses on the design, fabrication, testing and optimizing of a microfluidic h-filter based device for the magnetic-separation of tumor cells. The device has been fabricated using a 3d-printed mould with positive surface pattern and surface treated for better curing of PDMS near the mould’s surface.

Currently, the device is in testing and optimization phase and will soon be converted to an entirely 3D Printed device for supporting the manufacturability of the device.
