Microscale rockets can travel through cellular
landscapes

A new study from the lab of Thomas Mallouk shows how
microscale “rockets,” powered by acoustic waves and an onboard
bubble motor, can be driven through 3-D landscapes of cells and
particles using magnets. The research was a collaboration between
researchers at Penn and the University of San Diego, the Harbin
Institute of Technology in Shenzhen, and Pennsylvania State
University, where the study was initially conducted, and was
published in Science Advances.
