Flow cytometry analysis of MDA-MB-231 cells after photothermal therapy treatments under different treatment conditions.

Notes: The living cell fraction is negative for both Annexin V-FITC and propidium iodide. An earlier stage of apoptosis is linked with positive Annexin V-FITC labeling only. Double-stained cells were considered as necrotic/late apoptotic cells. The concentration of TMSG was 70 μg/mL, and the power density of laser irradiation was 3 W/cm².

Abbreviations: TMSG, tLyp-1 peptide and polyethylene glycol-comodified mesoporous silica-coated gold nanorods; PI, propidium iodide; FL, fluorescence; MDA-MB-231 cells, MD Anderson-metastatic breast-231 cells; min, minutes.
