A magnetic actuated, biomimetic microdevice for isolating biological entities in microwells. (A) A schematic of the microdevice that integrates three layers: Top plate containing an array of microwells (inset, scale bar-25 µm), bottom plate containing an array of micropillars (inset, scale bar-25 µm), and spacers placed in between the top and bottom plates to form a chamber for movement of the magnetic liquid marble. (B) Functioning of the microdevice is shown. An opening of shell around the magnetic liquid marble along with the movement in the microdevice to allow capturing of biological entities in the microwells is shown. (C) A schematic representation of captured biological entities in microwells after the operation of the microdevice.
