Figure 1. Topological characterization of nanoparticles. A) Transmission electron microscopy results of chitosan nanoparticles. The absolute diameters of chitosan nanoparticles were around 100±10nm. B) TEM microscopy of rh-EGF chitosan nanoparticles had particle diameters of around 100±50nm. C) _­The result of measuring the size of the conjugated nanoparticles with rh-EGF protein using the DLS method and its analysis.
