Magnetically driven rotation (IMAGE)
Caption
A schematic diagram of the magnetic rotary microfilter on a flat surface is shown in (a). The rotary microfilter is magnetically turned in a liquid environment on the flat surface by applying a uniform magnetic field with different orientations (b). A schematic diagram of manipulating magnetically rotary microfilter in channel is shown in (c) and demonstrated in an alcohol solution (d).
