Do the locomotion : Direct conversion of light energy into mechanical work is possible using photoresponsive compounds. A new report by Baigl and co‐workers shows how photoresponsive surfactant molecules (red and blue in the picture; γ is the surface tension) can be harnessed to move oil droplets resting on an aqueous solution, thus paving the way to exciting applications in microfluidics.
