Table 1 Average hydrodynamic diameters and zeta potential of STNPs suspensions

From: Intestinal toxicity evaluation of TiO2 degraded surface-treated nanoparticles: a combined physico-chemical and toxicogenomics approach in caco-2 cells

  In distilled water
(pH = 8 ± 0.3)
In the serum-free culture medium
STNPs Hydrodynamic diameters (nm) Zeta potential (mV) measured Hydrodynamic diameters (nm)
T-Lite 347 +/− 69 n/a 391+/−15
T-Lite DA 688 +/− 209 −2 +/− 5 723+/−63
T-Lite DL 237 +/− 26 −25 +/− 4 1353+/−231
  1. The STNPs were diluted to 100 μg/mL (T-Lite and T-Lite DA) or 10 μg/mL (T-Lite DL) in distilled water or serum-free culture medium. The measurement was made by DLS and zeta potential measurements.
