    Abstract: Provided are a pump unit and a centrifugal microfluidic system including the pump unit. The pump unit includes a gas generating agent. The gas generating agent includes a plurality of heating particles generating heat by absorbing energy and one of a sublimation material, azide, and azo compound mixed with the heating particles. When energy is supplied to the gas generating agent, the gas generating agent generates gas due to heat emitted from the heating particles to increase an air pressure around the gas generation agent so that the fluid is moved by the increased air pressure.

    Abstract: Provided is a droplet dispensing device having a nonconductive capillary nozzle. The droplet dispensing device comprises: a nonconductive capillary nozzle disposed in a downward position; a pump connected with the nonconductive capillary nozzle through a hermetically sealed fluid tube and generating a negative pressure to decrease the influence of gravity on a solution within the nonconductive capillary nozzle and the fluid tube; and an open circuit voltage supplier applying a voltage to the solution. The droplet dispensing device supplies the solution by capillary force to regularly maintain the shape of a droplet surface in the tip of the nonconductive capillary nozzle without using a separate driving device.
