Table 1 Summary of TEM, CLS and DLS measurements performed in water. Dcore: Diameter measured by TEM, D calc core calculated value of Dcore corresponding to a core-shell structure of apparent density ρapp composed of a core of density 19.3 g.cm-3 and a shell of density 1.064 g.cm-3 (nominal density of the CLS gradient)
