Abstract
A digital microfluidic chip, a method for driving the same, and a digital microfluidic device are provided. The digital microfluidic chip includes a state transition layer configured to bear a droplet, and a light driving layer configured to provide light for controlling a lyophobicity-lyophobicity transition of the state transition layer to drive the droplet to move. The light driving layer includes light emitting units arranged in an array and provides light. The state transition layer realizes a lyophobicity-lyophobicity transition. The light driving layer controls the lyophobicity-lyophobicity transition by providing light to drive the droplet to move. An existing digital microfluidic chip has a complex structure and a high fabricating cost, while the digital microfluidic chip of the present disclosure has a simple structure, a simple fabricating process and a low fabricating cost, and can realize miniaturization and integration to a maximum extent.
