Size characterization of the polymeric nanoparticles using dynamic laser light scattering (DLS) and transmission electron micrograph (TEM) studies. (A) DLS of the polymeric nanoparticles confirms a narrow size distribution in the 50 nm range. All the data analysis was performed in automatic mode. Measured size was presented as the average value of 20 runs. B) TEM picture demonstrates particles with a spherical morphology, low polydispersity, and an average size of 45 nm, comparable to what is observed in the DLS studies.
