Grow with the flow: bottom-up synthesis of anisotropic plasmonic nanoparticles within microfluidic channels

Abstract

Bottom-up colloidal synthesis is the "gold standard" approach for preparing plasmonic gold nanomaterials with select compositions, sizes, and shapes, with high uniformity.1 Here, we take a chemical approach towards translating traditional colloidal synthesis to in situ growth - the direct formation of morphology-controlled nanostructures directly on a substrate surface.
