The cell viability of HAECs incubated with hollow gold nanoshells. Data are expressed as mean ± SD from independent experiments. Control values from HAECs incubated without hollow gold nanoshells were defined as 1. a HAECs were incubated with DMEM containing the gradient concentrations of hollow gold nanoshells for 24 h (0.008 to 0.8 μg/mL). b HAECs were incubated with DMEM containing 0.8 μg/mL hollow gold nanoshells for the indicated times (4, 24, 48, 72 h). *p < 0.05 vs. control
