Tuning the In Vivo Transport of Anticancer Drugs Using Renal-Clearable Gold Nanoparticles.

ABSTRACT: Precise control of in vivo transport of anticancer drugs in normal and cancerous tissues with engineered nanoparticles is key to the future success of cancer nanomedicines in clinics. This requires a fundamental understanding of how engineered nanoparticles impact the targeting-clearance and permeation-retention paradoxes in the anticancer-drug delivery. Herein, we systematically investigated how renal-clearable gold nanoparticles (AuNPs) affect the permeation, distribution, and retention of the anticancer drug doxorubicin in both cancerous and normal tissues. Renal-clearable AuNPs retain the advantages of the free drug, including rapid tumor targeting and high tumor vascular permeability. The renal-clearable AuNPs also accelerated body clearance of off-target drug via renal elimination. T
