Figure 4From: Sub-chronic toxicity study in rats orally exposed to nanostructured silicaVisco-elastic behavior of SAS and NM-202 in the feed mixture after in vitro digestion. Higher storage moduli (G’) of (A) SAS and (C) NM-202 than loss moduli (G”) of (B) SAS and (D) NM-202 (as a function of the strain) indicate increasing gel-like properties, with increasing SiO2 concentrations.Back to article page
