Growth kinetics of human MZF-7 breast carcinoma cells incubated with functionalized gold nanoshells as monitored by the xCELLigence system: Cells treated with (a) MZF@sil@Au-DMSA; (b) MZF@sil@Au-TG; (c) MZF@sil@Au-MUA; (d) MZF@sil@Au-MTAB of given concentrations. The negative (vehicle) control was treated with sterile deionized water, whereas the cells treated with 5% DMSO and 0.5 μM doxorubicin were used as positive controls. The yellow vertical line marks the time point of the treatment.
