Figure 1. Formulation and characterization of various sized DiD-loaded PLGA NPs.

Figure 1.

(A) PLGA NPs are formulated by injecting ACN, PLGA, 0.5 wt% DiD and 2% PVA into the NanoAssemblr™. NPs are washed in water immediately following formulation. (B) Hydrodynamic diameter, PDI, and zeta-potential of NP formulations. Data is shown as mean ± SD (n = 3). SEM images of (C) NP-1 (D) NP-2 (E) NP-3 and (F) NP-4. Scale bar on images represents 1 μm.
