Recent Advancement in Functional Core-Shell Nanoparticles of Polymers: Synthesis, Physical Properties, and Applications in Medical Biotechnology
Figure 28
Schematically the drug diffusion mechanism from the core-shell nanoparticles is shown. The drug diffused out of closed (a and c) and opened (b and d) nanoparticles. Systems with no enthalpic interactions (a and b) are compared with systems which penalise both drug diffusion out of and bulk fluid into the polymer core (c and d).
