His innovative approach combines electrical resistance measurements with advanced imaging techniques to identify cancerous blood cells.

Latest Patents

Abdullah Yousif Obaid holds a patent for a method of detecting leukemia. This method involves placing a suspension of red blood cells in a reservoir that has a capillary tube partially immersed in it. An alternating current is applied to electrodes, one located in the reservoir and the other in the capillary tube, at different frequencies. The electrical resistance is measured at the interface between the electrode and the suspension in the capillary tube. Simultaneously, CCD (charge coupled device) cameras capture images from both top and side views. The electrical resistance reveals a peak at a characteristic resonant frequency, which differs for cancerous blood cells compared to normal ones. The CCD images display a pattern of maximum repulsion from the electrode at the resonant frequency in the top view, and a minimum height of blood cells on the side of the electrode at the resonant frequency in the side view.
