Retracted Article: Dynamic Adsorption Self-assembly of Au nanocube (NC) for opposite charge Au nanoparticles (NPs) in real time

Abstract

Using in situ liquid cell TEM imaging, the dynamic process of dimer and trimer formation were captured. The kinetic energy of NPs and the NC- Electrostatic Shielding Length (NC-ESL) are key factors to determine the self-assembly success or not. The symmetrical shape of NC shows the isotropy of electrostatic force.
