摘要

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