“…Still, their use is constrained by poor solubility, permeability, physiological instability, low bioavailability, and less-than-ideal flavor profiles (such as bitterness) [ 44 ]. Drug delivery systems based on nanotechnology have been investigated to see whether they can circumvent these drawbacks [ [45] , [46] , [47] , [48] , [49] , [50] , [51] , [52] , [53] , [54] ]. Nanostructured drug delivery devices have superior physicochemical and biological features to their microscale counterparts [ [38] , [39] , [40] , [41] , [42] ].…”
