Study of surface-modified PEGylated dendron-based copolymers with -NH2, -COOH, -Ac and -OMe end-group functionalities.  It was demonstrated that the micelles did not exhibit charge-dependent cellular interactions as expected which could be a result of high molecular weight to surface ratio and/or the orientation of the end groups (H-bonding).  In addition, the dendron micelles were found to be nontoxic up to concentrations of 100 uM making them potential drug delivery systems.
