Density gradient ultracentrifugation for colloidal nanostructures separation and investigation

(Science China Press) Density gradient ultracentrifugation (DGUC), as an efficient way of sorting colloidal nanoparticles, can realize the separation according to their differences in chemistry, structure, size and/or morphology. A recent review systematically introduces the development of DGUC in colloid nanoparticles' separation, purification, ultraconcentration and reaction mechanism study.
