Figure 1. A) Picture showing the stability after 2 months at 4°C of the
different PDA-PAR30 NPs formulations using different
concentrations of dopamine hydrochloride (0.5, 0.3 and 0.2
mg.mL-1) with a defined concentration of polyarginine
(PAR) of 1 mg.mL-1. B). Typical image of
PDA-PAR30 0.2 NPs obtained Transmission Electron
Microscope (TEM) and the subsequent size quantification results. C)
Results of zeta potential measurements performed on
PDA-PAR30 0.2 NPs as compared to pure PDA particles.
