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.
