Bone Regeneration from PLGA Micro-Nanoparticles

Figure 5

Electrophoretic mobility versus pH for PLGA nanoparticles with different characteristics. () PLGA, () PLGA/poloxamer188 blend, and () PLGA covered by Immuno-γ-globulin. The different surface composition affects the electrokinetic behaviour of bare nanoparticles. Surface charge values were screened by the presence of nonionic surfactant as poloxamers, or, in a higher extension, by the presence of antibody molecules attached on the surface.
