Abstract

See full text

Provided are an active droplet generating apparatus capable of controlling a droplet size, a method of controlling a droplet size using the same, and a self-diagnosis apparatus for diagnosing generation of a droplet, the active droplet generating apparatus including: a disposable microchannel upper plate; a multifunctional lower plate separated from the disposable microchannel upper plate and configured to be permanently used separately from the disposable microchannel upper plate; a functional polymeric film provided on a lower surface of the upper plate; a negative pressure forming means; and a flow velocity control device configured to adjust the droplet size to a desired size by receiving, by feedback, the voltage value measured by the droplet measuring electrode and controlling flow velocities of the oil and the sample, thereby controlling the droplet size in a feedback control manner by quickly and accurately measuring the droplet size using a capacitance impedance technique.
