Figure 2. The release rate of active ingredients as a function of the type of nanoparticle formulation

The release rate of active ingredients as a function of the type of nanoparticle formulation; an active-enriched a) shell or core affects the release rate. A less solid NLC (Formula C in Figure 2b) shows an even higher release rate but is slow relative to the immediate release observed from c) emulsion or gel-type formulations; sources: a) and b), Reference 6; c), Reference 7.
