Abstract: Nanoformulations derived from natural products are gaining popularity as a treatment option for several
human diseases, including cancer, as they offer a viable alternative to conventional cancer therapies, which are often
associated with numerous side effects and complications. Quercetin (Que), a plant-derived phenolic molecule, has
demonstrated potential as a chemotherapeutic agent for different types of cancer. However, Que's low water solubility,
instability towards antioxidants, low bioavailability, and severe biotransformation constraints make it challenging to
use in vivo. Nanoparticles have emerged as a promising technology for the precise targeting of tumor cells, leading to
improved efficacy and specificity in cancer therapies. In this review, the impact of flavonoid nanoformulations on
enhancing the safety, therapeutic potential, and bioavailability of Que in cancer treatment is highlighted. A variety of
nanoparticle types have been developed, including polymeric micelles, liposomes, PLGA nanoparticles, coencapsulation,
chitosan NPs, lipid carriers, silver and gold NPs, inorganic NPs, organic metal frameworks, and biomacromolecule-
based NPs, all aimed at improving the antineoplastic efficacy of Que. These nanoparticles offer several
advantages, including prolonged circulation time, tumor-specific biodistribution, high encapsulation efficiency, enhanced
therapeutic efficacy, and controlled release. This review provides fresh insights into the arena of drug discovery
for tumor therapies by focusing on the influence of flavonoid nanoformulations on the enhancement of their safety,
therapeutic, and bioavailability characteristics.
