Fig. 1From: The agglomeration state of nanoparticles can influence the mechanism of their cellular internalisationSize distribution of Rubipy-SiO2 NPs in complete cell culture medium. Rubipy-SiO2 NPs were suspended in CaCo-2 complete cell culture medium (10% of serum) at concentration of 1 mg/ml and the size distribution was evaluated either immediately or after 24 h pre-incubation at 37 °C by CLS (a) and by TEM (b)Back to article page
