Ultra-small natural product based coordination polymer nanodots for acute kidney injury relief.

ABSTRACT

Acute kidney injury (AKI) is frequently associated with reactive oxygen species (ROS) and causes high mortality in clinics annually, and nanotechnology-mediated antioxidative therapy is emerging as a novel strategy for AKI treatment. Herein, four kinds of natural antioxidants are able to coordinate with iron (Fe) ions to form ultra-small coordination polymer nanodots (CPNs) with good water dispersibility and strong ROS scavenging ability. In particular, Fe-curcumin CPNs (Fe-Cur CPNs) are applied for cellular ROS scavenging and rhabdomyolysis-induced AKI relief.
