Janus

 

Recent efforts to generate particles that propel themselves by consuming a reactant, or synthetic “swimmers,” have garnered great interest, with potential applications in medical and pharmaceutical industries and environmental remediation. In this study, Jalilvand and co-authors probed the motion of patchy and Janus particles near a wall. The terms “Janus” and “patchy particles”  refer to spherical particles that are 50% or less coated with a thin layer of metal, for example, platinum. Platinum catalyzes the decomposition of H2O2 leading to a reaction-driven motion of the particles. The work illustrates that the CCNY team, lead by Prof. Ilona Kretzschmar, has the ability to precisely engineer the motion of particles by controlling their surface properties.
