Microfluidic devices can take standard medical lab procedures and condenses each down to a microchip that can balance on top of a water bottle lid. A team from Michigan Technological University, studying chemical engineering, electrical engineering and materials science, streamline the design of microfluidic devices to be see-through to observe their inner workings. Using hair-thin tunnels and equally tiny electrodes, these devices funnel fluids through an electric current to sort cells, find diseases, and run diagnostic tests.
