Jin publishes in Nature Communications

3d helical particle motion

Jin’s project on active particle propulsion has been published in Nature Communications (DOI: 10.1038/s41467-019-10579-1), on June 12, 2019, as well as receiving a highlight in Nature Nanotechnology (https://www.nature.com/articles/s41565-019-0509-8). Using low-symmetry metal patches, we showcase the motion of AC field-powered active particles through 3D paths of tunable trajectory and speed. We show helical trajectories obtained with triangular patches, which enhance particle transport through porous membranes.

This work is fruit of our collaboration with Dr. Bishop from the Chemical Engineering Department at Columbia University and Allan Brooks (grad student at Penn State), as well as Dr. Shelton from our Department at LSU.
