Janus Micromotors: Visible Light Actuated Efficient Exclusion Between Plasmonic Ag/AgCl Micromotors and Passive Beads (Small 44/2018)

In article number 1802537, Larysa Baraban, Denys Makarov, and co‐workers present novel plasmonic Ag/AgCl‐based spherical Janus micromotors and investigate their collective behavior upon interaction with nonmotile passive beads. An efficient exclusion behavior between Ag/AgCl micromotors and the surrounding passive beads is observed under visible light illumination in pure H2O. The exclusion effect is tunable by the number of catalytically active Janus particles forming a micromotor, which is demonstrated experimentally and using molecular‐dynamics simulations.
