Albumin-Modified Cationic Nanocarriers To Potentially Create a New Platform for Drug Delivery Systems
Cationic nanocarriers have emerged as promising nanoparticle systems for the effective delivery of nucleic acid and anticancer drugs to cancer cells. A positive charge is desirable for promoting cell internalization, whereas it also causes some adverse effects, such as toxicity and rapid clearance by mononuclear phagocytic systems. Herein, a new strategy of modifying cationic polymer micelles with albumin forming a protein corona to improve the surface physiochemical properties is reported. The corona with a monolayer or a multilayer was constructed depending on the albumin concentration, and the proteins would denature in different degrees due to the interaction with the surface of cationic micelles. It is demonstrated that multilayer albumin corona is beneficial to prevent macrophage uptake, increase accumulation in tumor tissues, and reduce toxic side effects to normal tissues. Our work provides a promising method to modify the cationic nanoplatform by optimizing the biosecurity and bioavailability for potential application in drug delivery.
