Electrostatic Orientation of Optically Asymmetric Janus Particles.

ABSTRACT: Janus micro- and nanoparticles, featuring unique dual-interface designs, are at the forefront of rapidly advancing fields such as optics, medicine, and chemistry. Accessible control over the position and orientation of Janus particles within a cluster is crucial for unlocking versatile applications, including targeted drug delivery, self-assembly, micro- and nanomotors, and asymmetric imaging. Nevertheless, precise mechanical manipulation of Janus particles remains a significant practical challenge across these fields. The current predominant methods, based on fluid flow, thermal gradients, or chemical reactions, have their precision and applicability limited by the properties of their background fluids. Therefore, this study proposes electrostatics to deliberately control the local orient
