Chip to Evaluate Health of Immune System from Blood Sample

October 17, 2019 / medgadget

Knowing how well a patient’s immune system is functioning may be very useful in diagnosing a disease and guiding the course of therapy. Researchers from Nanyang Technological University in Singapore are making this a reality, having developed a hybrid chip that assesses the health of white blood cells in a whole blood sample. The microfluidic chip has a series of components that separate white blood cells from all the other components of blood. Thousands of cells can be processed in just a few minutes thanks to a mechanism resembling a coin sorting machine. Impedance sensors within the device are used to analyze individual white cells, which indirectly measure the size of the cell.
