In vivo NIR fluorescence imaging of HT29 tumor-bearing mice injected with 200 pmol of NT4-QDs (n = 3) and nude QDs (n = 3). ROI Fluorescence intensity (a) and tumor-to-background ratio (b) measured at different time intervals in mice injected with NT4-QDs (light grey) or QDs (dark grey). The data is represented as mean ± SD. *p < 0.05 compared to mice injected with unconjugated QDs (two-tailed Student’s t test and GraphPad Prism 5)
