From: Toxicity of CdSe Nanoparticles in Caco-2 Cell Cultures
Effects of synthesized CdSe QDs after removal of free Cd2+ on Caco-2 attachment and viability. The cell attachment and viabilities were analyzed by Live/Dead fluorescent labeling. Attached live (A) and dead (B) Caco-2 cells after dosing with synthesized CdSe QDs. Attached live (C) and dead (D) Caco-2 cells after dosing with SGF-treated synthesized CdSe QDs (concentrations were influenced by dilution during SGF treatment). Data are expressed as the mean ± SE from three separate experiments using cells of different cultures. Statistically significant differences in attached cell number (either attached live cells or attached dead cells) between a certain QD dose and other doses within the same type of QD are indicated by an asterisk (*) (p < 0.05). Statistically significant differences in attached cell number (either attached live cells or attached dead cells) between a certain type of QD and all other types of QD within the same dose are indicated by a pound symbol (#) (p < 0.05).
