Title: GEMBE Device
Description: Illustration of a GEMBE device: a complex biological sample such as dissolved dirt or whole blood is pushed by an electric field toward a microchannel. Buffer fluid flowing in the opposite direction acts as a gate. Gradually reducing the bufffer flow slowly 'opens' the gate, allowing individual components from the sample to enter the microchannel when the pressure becomes weaker than the electric force pushing each component molecule. These molecules then travel past a detector that analyzes them. Unwanted components are kept out of the microchannel.
