Fig. 3. Cytotoxicity and phototoxicity of the THP-AuNR nanoprobe. (A) Cell viabilities after incubation of MCF-7 and MDA-MB-231 cells with the THP-AuNR nanoprobe at various concentrations for 24 h. (B) Cell viabilities of MCF-7 cells after incubation with and without the THP-AuNR nanoprobe induced PTT for different lengths of time. (C) Fluorescence images of calcein AM/PI-costained MCF-7 cells incubated with the THP-AuNR nanoprobe and the control treated with and without the NIR laser. Scale bars: 1 mm.
