Figure 3: Polymeric microparticles formulated by single- (a) and double- (b, c, and d) emulsion method. Images obtained through confocal laser scanning microscopy of (a) FITC-loaded poly(lactide-co-glycolide) (PLGA) microparticles (MPs) (green), (b) NBD-cholesterol (green), and Texas-Red (red) loaded PLGA microparticles. (c) Transmission electron microscopy (TEM) of ceftiofur-loaded poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) microparticles; (d) scanning electron microscopy (SEM) of florfenicol-loaded PHBV microparticles.
