Figure Lengend Snippet: ( a ) Schematic image of biomimetic non-magnetic swimmers. The length of the head and tail of the designed polymer swimmer is ≈400 μm and ≈1500 μm, respectively. The self-propulsion speed reaches ≈10 μm/s. ( b ) The concept of manufacturing magnetic nanorods with a flexible polymer hinge. The image shows the flexible part of the polyelectrolyte shell connecting two Ni/Au/Pt segments. ( c ) Schematic and SEM image of 3-link swimmers . Copyright 2012, American Chemical Society. The graph shows the dependence of the average propulsion speed on the frequency for 3-link swimmers. ( d ) Three-dimensional laser lithography and deposition of a Ni layer for magnetic actuation. The microswimmer made in IP-L 780 polymer using 3D laser lithography and the deposition of a Ni layer for magnetic actuation . The total length of the microswimmer is 120 μm and the length of its magnetic head is ~40 μm.
