Fig. 2: Shape-shifting and motility of hybrid magnetic organic crystals.
From: Remote and precise control over morphology and motion of organic crystals by using magnetic field

a, b Photographs of MNP//4 and MNP//5 that were reshaped by using magnetic field observed under UV light. Note that the contrast of the color in these images was enhanced for clarity. c Example of an inchworm-like motility of MNP//4 induced by a temporally evolving spatial gradient in the magnetic field. The white scale bar corresponds to a length of 1 cm. Note that the contrast of the color in these images was enhanced for clarity.
