After the publication of this work [1] it was noticed that the values in Tables 4 and 5 were incorrect. The numbers should have been all multiplied by 10.

Table 4 Cerium concentration in different tissues at 2 hours after intravenous injection of uncoated or silica-coated CeO2 NPs
Table 5 Cerium concentration in different tissues at 2 days after intravenous injection of uncoated or silica-coated CeO2 NPs

Please see below corrected tables 4 and 5.
