D-Glucosamine Conjugation Accelerates the Labeling Efficiency of Quantum Dots in Osteoblastic Cells

Figure 2

Many QDs (green fluorescence) are labeled inside the cells after one day of culture with D-glucosamine. Note the lack of overlap between the QDs and lysosomes (fluorescent red dots). Scale bar = 15 μm.
