Abstract

A fork-like molecule can induce citrate-capped gold nanoparticles of 2.6 nm diameters to form sintered peanut-like nanoarrays and aggregates. The formation of such aggregates is size-dependent because of steric hindrance between the fork-like molecule and the 5 nm or bigger Au nanoparticles.
