In vitro phototoxicity studies of QDs-RGD-PDT-induced pancreatic cancer cell death.

Notes: (A) TEM images of QDs-RGD, scale bar: left, 100nm; right 50nm; (B) Absorption spectra of QDs-RGD; (C) Fluorescence emission spectra of QDs-RGD; (D–F) Cell apoptosis assay of different concentration (D), incubation time (E) and light dose (F) measured by CCK-8. Data are expressed as means ± SEM (n = 3). **P < 0.01, ns, not significant.

Abbreviations: QDs-RGD, quantum dots conjugated with arginine-glycine-aspartic acid peptide sequence; PDT, photodynamic therapy; TEM, transmission electron microscopy; CCK-8, cell counting kit-8; SEM, standard error of the mean.
