Fig. 7From: Stimuli-disassembling gold nanoclusters for diagnosis of early stage oral cancer by optical coherence tomographyOCT and DvOCT imaging of dysplastic hamster check pouch with acid-disassembling Au NCs. Images of DMBA-applied, early-stage dysplastic hamster cheek pouch, obtained by SD-OCT (a) and DvOCT (b) after administering acid-disassembling Au NCs. Scale bar: 100 µm. The images were taken before (base) and 20 and 40 min after administering acid-disassembling Au NCs. The color-coded Doppler variance in DvOCT images of early-stage dysplasia (5 dotted regions) was quantified and compared with that of normal tissue (c) (yellow area: epithelial layers)Back to article page
