Plant-derived edible nanoparticles (PDNPs) are nano-sized membrane vesicles released by edible plants, such as grapefruit, ginger, broccoli, and lemon. They are non-toxic, have tissue-specific targeting properties, and can be mass-produced. Thus, they have great potential for clinical application. PDNPs offer multiple advantages over the currently available drug delivery systems, such as their relatively high internalization rate, low immunogenicity, proven stability in the gastrointestinal (GI) tract, and ability to overcome the blood-brain barrier but not cross the placental barrier. In this review, we will discuss these merits of PDNPs and analyze the current issues in PDNP research.
