Flip-Flops of 1 µm PS / 100 nm Au JPs were performed by time triggering the switching frequency between flip and flop. Perfomance rotations were up to 20 Hz.embedded by Embedded Video
Janus particles are particles that are different on each side on a chemical of physical point of view.
We have created 1 µm PS/100nm AU JPs and trapped them with DEP in 3D. We have shown that rotation around their axis can be controlled by changing the applied potential frequency or voltage.embedded by Embedded Video
Using dielectrophoresis to repeal particles from squared like electrodes on the top and bottom of the microfluidic channel. PS 1µm, f=2MHz and Vp-p=20 Vembedded by Embedded Video
Using dielectrophoresis, particles of polystyrene 1 µm were focalized with an AC potential applied on 4 funnel shaped ITO electrodes. f=2MHz and Vp-p=20Vembedded by Embedded Video
