Evaluation of delivery efficiency of AlPcS₄ carriers in SGC-7901 cells.

Notes: (A–F) Total fluorescence intensity of free AlPcS₄ at 0.25–4 µg/mL in cell solution (A) and intracellular fluorescence intensity of AlPcS₄ (B), F127–AlPcS₄ (C), Clip–AlPcS₄ (D), AuNR–AlPcS₄ without irradiation by 808 nm laser light (E), and AuNR–AlPcS₄ with irradiation by 808 nm laser light (F) at 0.5–8 µg/mL after treatment on SGC-7901 cells for 6 hours, respectively. (A1–F1) The correlation between concentration and fluorescence intensity of free AlPcS₄ (without uptake in cells, A1), AlPcS₄ (uptake in cells, B1), F127–AlPcS₄ (uptake in cells, C1), Clip–AlPcS₄ (uptake in cells, D1), AuNR–AlPcS₄ (uptake in cells and without irradiation by 808 nm laser light, E1), and AuNR–AlPcS₄ (uptake in cells with irradiation by 808 nm laser light, F1), respectively. The experiment was repeated three times. The data represent the average of three experiments and the error bars show SD.

Abbreviations: AlPcS₄, Al(III) phthalocyanine chloride tetrasulfonic acid; AuNR, gold nanorods; Clip, cationic liposome.
