Fig. 4From: Curcumin-Loaded Nanoparticles with Low-Intensity Focused Ultrasound-Induced Phase Transformation as Tumor-Targeted and pH-Sensitive Theranostic Nanoplatform of Ovarian Cancera The confocal fluorescence images of cells treated with free FITC and FITC labeled FCP, FA-FCP + FA and FA-FCP. Green and blue colors represented FITC and DAPI fluorescence, respectively. Scale bar = 60 um. b The FITC fluorescence signal statistical data inside cells treated with free FITC and FITC-labeled FCP, FA-FCP + FA and FA-FCP by FCM. **p < 0.01, compared with the other groups. c The confocal fluorescence images of cells treated with FITC-labeled FA-FCP and lyso-tracker red. Green, blue and yellow colors represented FITC, DAPI, and green/blue merged fluorescence, respectively. Scale bar = 60 umBack to article page
