“…In fact, CUR belongs to Class IV of the Biopharmaceutics Classification System (BCS), whose solubility is about 7.8 µg mL −1 , which can be improved by various strategies of synthesizing appropriate formulations (e.g., solid lipid nanoparticles, solid dispersion, colloidal drug delivery systems, microemulsions, and multi-component crystals) [24]. Encapsulation of CUR within materials, such as CS-based materials, is a strategic approach to improve its dispersibility in aqueous media, chemical stability, controlled release ability, bioactivity, and, thus, use in therapeutic treatment [4,26,28,29]. By way of example, Asif et al [30] reported the synthesis, characterization, and in vitro study of CUR-loaded CS-nanoparticles to enhance the solubility and bioavailability of CUR and to determine the anti-inflammatory and anti-arthritic activities.…”
