Review: Biofunctionalized Quantum Dots in Biology and Medicine

Figure 9

3D reconstruction of laser scanning confocal microscopy image of biofilm sample. Green represents the green fluorescence protein (GFP) of Pseudomonas aeruginosa, red represents carboxylated QDs (em = 655 nm) and blue represents fluorescent labeled lectin which recognizes fucose (a polysaccharide common in biofilms). Note that the QDs appear to be most closely associated with bacterial surfaces and not fucose.
