In vitro toxicity of POSS and MSA-QDs to Hep G2 cells.

Notes: Different concentrations of QDs were compared to the control group. Both POSS and MSA-QDs are biocompatible at 2.5 μg/mL at 1 and 24 hours. POSS-QDs show lower cell viability at 5 μg/mL at 24 hours compared to MSA-QDs, although there is no significant difference in cell viability between the 2 QDs at higher concentrations of 10 and 15 μg/mL. *P < 0.05; **P < 0.01.

Abbreviations: POSS, polyhedral oligomeric silsesquioxane; MSA-QDs, mercaptosuccinic acid quantum dots; QDs, quantum dots; POSS-QDs, polyhedral oligomeric silsesquioxane quantum dots.
