Abstract

A method for preparing a metal nanocube with a controlled corner sharpness index includes a step of reacting with a first surfactant and a predetermined surface-protecting agent. A method for preparing a metal nanocube aggregate having a purity of 95% or more includes a step of centrifuging in the presence of a second surfactant. A probe composition includes the metal nanocube or metal nanocube aggregate prepared by the method; and a gold (Au) nanocube having an average edge length of 20 nm or less.
