The design of scaffolds for solubilizing/dispersing poorly water-soluble bioactive molecules in neutral aqueous media is a major challenge of functional food, pharmaceuticals, and cosmetics development, as highlighted by the plethora of corresponding solubilization/dispersion strategies. Herein, renatured beta-1,3-1,6-glucan (r-glucan) nanoparticles prepared by neutralization of alkali-denatured beta-1,3-1,6-glucan and subsequent centrifugation are used as a host to disperse water-insoluble bioactive molecules (curcumin, all-trans-retinoic acid, and rebamipide) by simple mixing of host and guest solutions. Curcumin in the r-glucan cavity is found to be stacked in the form of J-aggregates and twisted along the helix, and is demonstrated to be retained for significantly longer than curcumin in the corresponding gamma-cyclodextrin (gamma-CD) complex. Specifically, curcumin incorporated in gamma-CD is released within 5.5 hours, whereas that in the r-glucan complex is released very slowly, with 12% of curcumin in the latter complex retained after 31-day incubation at 37 degrees C. Thus, inclusion protocol simplicity and slow release ability make r-glucan nanoparticles a potential carrier scaffold for various applications.
