“…Nevertheless, Mix‐O/W nanoemulsions represent a suited solution to absorption because they allow the intake of a high amount of curcumin together with a low fat content. Additionally, this study constitute a further proof to the validation of the in vitro simulated digestion process, in accordance with recent study (Cuomo et al., ), for the obtainment of important results regarding the encapsulation of lipophilic compound such as curcumin within food‐grade delivery systems.…”

“…Gastrointestinal model : The gastrointestinal fate of curcumin‐loaded nanoemulsions was studied through an in vitro digestion model mimicking oral, gastric, and small intestinal phases (Cuomo et al., ; Versantvoort, Oomen, Van de Kamp, Rompelberg, & Sips, ). The simplified digestion process has been simulated by replicating the physiological digestive status of the various fluids (saliva, gastric and intestinal juices), including the residence time for each phase.…”

“…Furthermore, these downsides may be overcome by encapsulating curcumin within food‐grade delivery systems such as liposomes (Chen et al., ), nanocomplexes (Chen, Li, & Tang, ), colloidosomes (Shah et al., ), emulsions (Aditya et al., ; Sari et al., ), nanoemulsions (Ahmed, Li, McClements, & Xiao, ; Patel & Velikov, ), or biopolymer nanoparticles (Hu et al., ; Xiao, Nian, & Huang, ). Among these strategies based on colloidal suspension for encapsulation and protection of compounds, the utilization of emulsions represents a good compromise to overcome the limits mentioned above (Cuomo et al., ; Cuomo, Ceglie, De Leonardis, & Lopez, ; Mosca, Murgia, Ceglie, Monduzzi, & Ambrosone, ). Nanoemulsions, in particular, are fine dispersions of oil droplet in water (Gurpreet & Singh, ) and are rapidly digested in the intestinal tract, thus, if the oil phase contains hydrophobic nutraceuticals, nanoemulsions can increase their bioavailability.…”

The potential of heterogeneous systems like oil‐in‐water (O/W) nanoemulsions is exploited as an oral delivery system for curcumin, a natural lipophilic compound with numerous health benefits. Two types of O/W nanoemulsions, one stabilized by sodium caseinate (Cas‐O/W), a surface‐active and emulsifying protein, and the other stabilized by a blend of caseinate and Tween 20 (Mix‐O/W), were loaded with the bioactive compound and tested through a simulated gastrointestinal digestion process to evaluate their effects on delivering of curcumin. It was first demonstrated that the amount of curcumin solubilized through Mix‐O/W nanoemulsion was higher than that in Cas‐O/W nanoemulsion. Cas‐O/W nanoemulsions, indeed, at their best, solubilized about 55 µg/mL of curcumin while Mix‐O/W nanoemulsions reached a curcumin concentration around 180 µg/mL. Furthermore, for both the systems an increase of curcumin loading capacity was recorded with the rise of incubation temperature. Finally, after the in vitro simulated digestion process, the potential curcumin bioavailability was evaluated and the data suggested that Mix‐O/W nanoemulsions provided more than twice the amount of curcumin compared to Cas‐O/W nanoemulsions. On balance, the outcomes of this investigation demonstrated that the mixed emulsifier system offered a higher amount of lipophilic compound with a low fat intake compared to nanoemulsions stabilized by sodium caseinate. Practical Application The outcomes of this study allow the recognition of the protein/surfactant‐stabilized nanoemulsions as a suitable solution to deliver curcumin. The nanoemulsions proposed here provide a high intake of curcumin, a lipophilic compound, with low fat content. The use of such delivery systems helps to overcome limits in oral bioavailability related with the scarce solubility of some compounds in food preparations and beverages.

“…The diameter of the curcumin-loaded anionic liposomes (without chitosan) was 129 nm with a PdI of 0.095 and zeta potential of -49 mV. The diameter and PdI were not altered after chitosan coating, whereas the surface charge became positive [138]. Both formulations were tested in the in vitro digestion model, including simulated saliva fluid, simulated gastric fluid, and simulated intestinal fluid, and showed that liposomes without chitosan were digested slightly more in simulated saliva fluid and simulated gastric fluid, whereas chitosan-coated liposomes were more highly digested in simulated intestinal fluid.…”

“…The presence of a positive charge on the chitosan-coated liposome surface results in an interaction with the negatively charged glycoproteins of mucin. This may result in their being covered by a layer of mucin and protection of the curcumin during the other phases of digestion, thus allowing greater curcumin absorption [138]. Solid lipid nanoparticles: solid lipid nanoparticles (SLNs) are another type of lipid-based nanocarrier.…”

One of the limitations of fluorescence probe molecules during biomedical estimation is their lack of ability to selectively determine the targeted species. To overcome this there have been various approaches that involve attaching a functional group or aptamers to the fluorescence probe. However, encapsulating probe molecules in a matrix using nanotechnology can be a viable and easier method. Curcumin (Cur) as a fluorescence marker cannot distinguish DNA and RNA. This research reports a novel selective approach involving the use of nanocapsules composed of liposomal curcumin coated with chitosan for the selective detection of RNA molecules using a fluorescence method. The increase in RNA concentration enhanced the electrostatic interaction between the negatively charge surface of RNA and the positively charged nanocapsule, which was further verified by zeta potential measurement. This method had a low limit of detection (36 ng/ml) and higher linear dynamic ranges compared with other studies found in the literature. Moreover, the method was not affected by DNA and was selective for the detection of RNA molecules for which the site of interaction was confined only to uracil. The selectivity for RNA molecules towards other analogues species was also examined and recovery range found was between 99 and 100.33%.
