Today, researchers have developed an ultrasound-based microfluidic platform that can accurately control the size and shape of airborne droplets. This platform could be used to deliver drugs and vaccines, as well as create low-cost, efficient, and accurate medical diagnostics. The platform can be tuned to produce droplets of different sizes, shapes and velocities, allowing for greater control over the delivery of medicines or other particulates. This research, led by Professor Jong-Beom Baek from the Korea Advanced Institute of Science and Technology (KAIST), is published in Science Robotics.
