Cytotoxicity analysis of HU2 cell line exposed to the CNPs. Analysis was performed by flow cytometry and according to Materials and Methods. A Control, B P, C P/2, D P/4, E P/8, F P/16, and G Survival rate of the cells normalized to the control. Q1 = Necrotic cells, Q2 = Late apoptotic or necrotic apoptotic cells, Q3 = Apoptotic cells, and Q4 = Untreated cells
