Size-dependant absorption characteristics of drug crystals and curcumin crystal formation. (a) Large drug crystals have poor absorption properties, whereas smaller particles (micro–nanometer) result in rapid dissolution and bioavailability. (b) Curcumin drug particle formation and conversion into precipitation in a bottom-up approach in an alcohol and water mixture with time. Reprinted, with permission, from [31].
