Abstract
The present disclosure discloses a microfluidic structure, a microfluidic chip and a detection method. The microfluidic structure includes: a first base substrate and a second base substrate opposite to each other, an antibody area located between the first base substrate and the second base substrate and storing an enzyme-labeled first antibody, a cleaning area storing cleaning liquid, a signal substrate area storing a signal substrate solution and a detection area with a second antibody and an ion sensitive film fixed thereon, wherein all channel areas from the antibody area, the cleaning area and the signal substrate area to the detection area each have a driving electrode structure driving liquid drops to move; and the detection area has a thin film transistor connected with the ion sensitive film.
