  • Title: Au@Prussian Blue Hybrid Nanomaterial Synergy with a Chemotherapeutic Drug for Tumor Diagnosis and Chemodynamic Therapy.
    Author: Hang L, Li H, Zhang T, Men D, Zhang C, Gao P, Zhang Q.
    Journal: ACS Appl Mater Interfaces; 2019 Oct 30; 11(43):39493-39502. PubMed ID: 31576732.
    Abstract:
    Recently, the chemodynamic therapy (CDT) has been widely reported and applied to tumor therapy. However, only low level hydroxyl radicals (•OH) generated by the endogenous hydrogen peroxide alone are insufficient to kill the cancer cells. To overcome the insufficient therapeutic effect, this study reports a novel CDT based on Fenton catalyst Au@Prussian blue nanocubes (Au@PB NCs), subsequently encapsulated with doxorubicin (Dox). The in vitro and in vivo results indicate that the Dox-Au@PB NCs can take synergistic effects on tumor suppressor by CDT. In addition, Au@PB NCs possess high X-ray computed tomography contrast enhanced efficiency about ∼27.13 HU·mL·mg-1. This study highlights a great potential of the Dox-Au@PB NCs for tumor diagnosis and CDT.
