SOG and ROS production in SGC-7901 cells treated with AlPcS₄ carriers or AlPcS₄.

Notes: (A, B) The fluorescence intensity of SOSGR probe or DCFH-DA probe measured to analyze SOG and ROS production in SGC-7901 cells treated with AlPcS₄, F127–AlPcS₄, Clip–AlPcS₄, AuNR–AlPcS₄, and AuNR–PEG–RRLAC and irradiated with laser light, at different concentrations (0.5–8 µg/mL). Data represent the average of three experiments and the bar is SD. (C and D) The relative increased trend of SOG and ROS production in SGC-7901 cells treated with AlPcS₄, F127–AlPcS₄, Clip–AlPcS₄, and AuNR–AlPcS₄ and irradiation with laser light, at different concentrations (0.5–8 µg/mL).

Abbreviations: AlPcS₄, Al(III) phthalocyanine chloride tetrasulfonic acid; AuNR, gold nanorods; Clip, cationic liposome; DCFH-DA, 2′,7′-Dichlorodihydrofluorescein diacetate; ROS, reactive oxygen species; RRLAC, arginine-arginine-leucine-alanine-cysteine peptide; SOG, singlet oxygen; SOSGR, singlet oxygen sensor green reagent.
