Zeta potential of modified dendrimer conjugates. Zeta potentials for G5-Alkyne-NH2 (1), G5-Alkyne-NHAc (2), G5-Alkyne-PEG3 (3) and G5-Alkyne-PEG7 (4) in Molecular grade water (a) and in 1 mM HEPES pH 7 buffer (b) are shown above. As expected, G5-Alkyne-NH2 (1) has the most positive charge. G5-Alkyne-NHAc (2), G5- Alkyne-PEG3 (3) and G5-Alkyne-PEG7 (4) are all similar in charge and are close to neutral in molecular grade water and in 1 mM HEPES pH 7.
