Fluorescent carbon dots grafted hyperbranched glycidyl ether.

In this paper, we presented a "grafting from" method to fabricate CDs-g-HPG core-shell nanostructures where the carbon dots were coveredbearing by a multi-hydroxy hyperbranched polyglycerol (HPG) shell. This method combed "grafting from" method with an anionic ring-opening polymerization technique. The prepared CDs-g-HPG have good water solubility, low biotoxicity and strong blue fluorescence, which exhibit great potential in drug delivery and bio-imaging. [ABSTRACT FROM AUTHOR]
