This document discusses the design of a device to detect blood cancers like leukemia through early screening. It will have a disposable microfluidic chip that separates blood cells and a reusable electrical detector. The chip will use electrical or pressure methods to separate normal and cancerous white blood cells. The detector will then check electrical resistance to provide a positive/negative result. Testing will optimize the design and check it against blood samples to detect cancers before symptoms arise. The goal is a low-cost, easy-to-use device that increases early detection rates for blood cancers.
