For example, improvement of the water solubility and
stability of curcumin can be achieved by encapsulation of curcumin
in media such as surfactant micelles [17], polymeric micelles [11],
hydrogels [12], microcapsules [13], and nanoparticles [14]. The
properties of curcumin can also be improved by interaction or
complexation with macromolecules [14] and chemical alteration
[15]. For example, Wichitnithad et al.
