Light lets microswimmers switch between bacteria-like and algae-like propulsion

Physicists at Leipzig University and Charles University in Prague have developed a method for changing the swimming style of tiny artificial microswimmers in real time. They can make a single microscopic particle switch at will between modes of swimming inspired by bacteria and algae. The researchers have thus turned a property that was previously fixed during production into a programmable parameter. They believe their findings pave the way for an evolutionary approach to the development of synthetic active matter. Their study has now been published in Nature Communications.
