Motorized droplets thanks to feedback effects

A team of physicists from Germany and Sweden working with first author Jens Christian Grauer from Heinrich Heine University Düsseldorf (HHU) has examined a special system of colloidal particles that they activated using laser light. The researchers discovered that self-propelling droplets, which they have named ‘droploids’, formed which contain the particles as an internal motor. They describe these droploids in more detail in the latest edition of the journal Nature Communications.
