Aptamer-mediated liver-targeted curcumin delivery system based on tetrahedral framework nucleic acids for NAFLD.

ABSTRACT: Curcumin is renowned for anti-inflammatory, antioxidant and hepatoprotective effects, and has been implicated in the amelioration of obesity and diabetes. Notwithstanding its considerable therapeutic potential, the clinical utility of curcumin is hampered by its suboptimal bioavailability, due to poor aqueous solubility and chemical instability. Consequently, the development of strategies to enhance the aqueous solubility, stability, and ultimately, the bioavailability of curcumin has been a focal point of intense research. This study harnessed tetrahedral framework nucleic acids (tFNAs), a relatively simple DNA nanostructure, to encapsulate curcumin. Meanwhile, novel aptamers for liver-specific targeting were acquired by SELEX (Systematic Evolution of Ligands by Exponential Enrichment) me
