Abstract
-factors through simple, scalable, and cost-effective electrostatic self-assembly processes, with practical implications in optical sensing and nanophotonics. Moreover, the ultra-uniformity achieved by our methods opens up new opportunities to study the far-field dipole couplings in random arrays of anisotropic AuNPs.
