Fig. 3. Non-magnetized microjets are not capable of pick-up of paramagnetic beads (dark spots) from their mixture with silica beads (transparent beads), moving through their mixture and ignoring them all. A, B and C represent time 0, 3 and 5 s of time frame. Scale bar of 50 μm. Conditions: 6% H2O2, 1% SDS, beads concentration approximates to 3 × 104 μL–1 for the silica beads and 1 × 104 μL–1 dynabeads.
