SEM Characterization Sizing Results. A. Narrow size distribution and high quality spherical shaped yield example in A at 2μm scaling. B. Close up 500 nm scaling image indicates narrow size distribution in the 200-350 nm range consistently for all manufactured yields. C. Nanoparticle average size by drug and polymer combination. Aspirin nanoparticles of either 50:50 or 65:35 type had greater size (p<0.05) versus prednisolone.
