The group of Yanlei YU at Fudan University has developed a novel concept for liquid handling. It is based on channels with deformable tubular microactuators containing azobenzene derivatives. Upon illumination, these channels change shape and drive the liquid into a desired direction, without any need for pumps. The new concept is expected to help design small-sized and portable instruments for blood tests at home.
