From: Formation of printable granular and colloidal chains through capillary effects and dielectrophoresis
(a) Direct deposition of a formed chain at a speed of approximately 0.2 mm s−1. Inset: Top view of a pattern formed by subsequent deposition of two individual chains. Particle size is of ∼55 μm. (b) Example of parallel deposition of chains composed of particles with different sizes, of ∼25, ∼55 and ∼100 μm, from left to right. (c–e) Examples of C-shaped, S-shaped and L-shaped pathways, composed of particles with sizes of ∼25, ∼15 and ∼15 μm, respectively. Scale bar, 100 μm.
