), a natural plat with known medicinal uses for more than 4000 years. Most turmeric therapeutic effects are attributed to curcumin, a yellow-coloured extract. Curcumin has received considerable attention due to its biological activities, such as its use in arthritis, liver and neurodegenerative diseases, obesity, and several types of cancers. Most of these curcumin therapeutic activities are related to its antioxidant and anti-inflammatory effects. However, the clinical application of curcumin is hampered by some limitations that prevent its extensive clinical application. Curcumin high hydrophobicity of curcumin and limited water solubility are among the most important limitations. This poor solubility will result in low bioavailability due to its poor absorption into plasma and the target tissues. Curcumin also has rapid metabolism, which will significantly lower its bioavailability and shorten its half-life. Moreover, curcumin is photosensitive with limited chemical stability during manufacturing and storage. These limitations have been overcome by applying nanotechnology using several types of nanoparticles (NPs). This includes using NPs such as liposomes, niosomes, gold nanoparticles, and many others to improve the curcumin solubility and bioavailability. This review focuses on the different types of NPs investigated and the outcomes generated by their use in the most recent studies in this field. To follow the latest advances in the field of site-specific drug delivery using nanomaterials, an electronic databases search was conducted using PubMed, Google scholar and Scopus using the following keywords: lipid-based nanoparticles, curcumin delivery, niosomes, and liposomes.
