Recently, we reported that nanogels of cholesterol-bearing pullulan (CHP) modified with amino groups(CHPNH2) acted as a novel carrier of quantum dots (QDs) for bioimaging. In this study, we investigated the formation of nanogel-QD complex and its potential application to live cell imaging. The size of the complex (304Qnm) varied depending on the types of proteins conjugated to QD. The complex nanopartides had little influence on cell function. The internalized QD into MSC were retained for 2 weeks. The results indicate that nanogel-QD complexes were versatile fluorescent probes for long-term cell imaging.
