Abstract:We report two viable strategies to assemble and manipulate arrays of nano- and micro-particles by means of topological defects (TDs) in anisotropic fluids. Exploiting different boundary conditions, single TD, 1D arrays of TDs are tailored in liquid crystal twist cells. In a first approach, light-guided control of particles captured in disclination lines is demonstrated involving the use of a photosensitive chiral dopant within a nematic host. In the second one, an applied voltage enables a continuous displacem… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
