From: Are quantum dots ready for in vivo imaging in human subjects?
Vasculature imaging with QDs. (a) Fluorescently labeled dextran gave blurred images of tumor vessels. (b) QD imaging yielded a sharp boundary between the vessel and interstitium. (c) Concurrent imaging of both QD and GFP (green) provides clear separation of the vessel from GFP-expressing perivascular cells. (d) Vessels highlighted with QD (red) were imaged simultaneously with the second harmonic generation signal from collagen (blue). Scale bar = 50 μm. From [129]
