(b) PGA-co-PDL NPs prepared at pH 7
(b) PGA-co-PDL NPs prepared at pH 7.0 by double emulsion with encapsulated PspA4Pro. lungs. PGA-co-PDL/HCl-CS (291 nm) or CM-CS (281 nm) NPs produced smaller sizes compared to PLGA/HCl-CS (310 nm) or CM-CS (299 nm) NPs. Moreover, NPs formulated with HCl-CS possessed a positive charge (PGA-co-PDL +17 mV, PLGA + 13 mV) compared to those formulated […]
