title: Controllable formation and TEM spatial visualization of cross-linked gold nanoparticle spherical aggregates.
abstract: Gold nanoparticles (NPs) were assembled and cross-linked into spherical aggregates by colloidal emulsion evaporation and ligand exchanging. The optical absorption, conventional transmission electron microscopy (TEM) and bright field (BF) TEM tomography confirm that the cross-linking of the pre-condensed aggregates generates high stability and compactness.
