Abstract
Hyperbranched poly(amido amine)s (HPAA) show weak photoluminescence, however, they have shown strong emission after short polyethylene glycol (PEG) chains have been linked onto HPAA macromolecule via Michael addition reaction. These PEGylated hyperbranched poly(amido amine)s show low cytotoxicity and potential application in cell imaging.
