SWNH–QD have minimal reduction in metabolic toxicity after 3- and 24-h incubation at 37 °C evaluated with alamarBlue^® assay (n = 3) in a AY-27, b MDA-MB-231, and c U-87 MG cell lines. Black bars represent the untreated control group while gray bars represent cells treated with 0.025 mg/mL SWNH–QD. Data represented as percent differences from the control (no nanoparticle) group determined by Eq. S1 in SI. *Denotes statistical difference from the control for p<0.05 and **denotes statistical difference for p<0.01 using Student’s t test
