Figure 7

1H NMR spectra and PLS-DA of liver tissue extracts from rats following an intravenous injection of silica nanoparticles (50 mg/kg body weight) at 48 hours. (A) 1H NMR spectra; (B) PLS-DA score plots derived from 1H NMR spectra; and (C) coefficient plots derived from 1H NMR spectra.

Notes: (a) Control and (b) silica nanoparticle (SiO2 NP)-treated group.
