Abstract
A scalable and single-step method exploiting capillary interactions for creating sub-100nm non-coalescent metallic(Ga) nanodroplets enabling controlled plasmon-hybridization, is shown herein. It enables tuneable gap-plasmonic resonances between the nanodroplets, thus allowing mechanochromic sensing and display applications.
