Physicists have built a magnetic-levitation device that can control the forces on tiny particles and droplets of liquid with much greater precision than existing methods. Igor Lyuksyutov and colleagues at Texas A&M University in the US say their technique could be used for both basic research and a range of applications.
The processor could be used to analyse droplets containing a variety of fluids, including biological cells, bacteria and viruses. Other applications include new types of micro- and nano-electromechanical systems, and experiments with aerosols and colloids.
