Research Description<\/span><\/h2>\n\n\n\n

\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nThe group has performed extensive work in using electric and magnetic fields as a tool for on-chip assembly and manipulation\nof nanoparticles, microparticles, and live cells. Their research has been among\nthe first to focus on Janus, patchy and cubic metallodielectric particles.A new AC-electrokinetic mobility mode of Janus metallodielectric\nparticles was discovered. Means to form percolated networks by induced\nmultipolar interactions hold promise for numerous new materials. \n\n\n\n<\/p>\n\n\n\n
