Levitation has long been a staple of magic tricks and movies. But in the lab, it’s no trick. Scientists can levitate droplets of liquid, though mixing them and observing the reactions has been challenging. The pay-off, however, could be big as it would allow researchers to conduct contact-free experiments without containers or handling that might affect the outcome. Now, a team reporting in ACS’ Analytical Chemistry has developed a method to do just that.
