A Self-Disguised Nanospy for Improving Drug Delivery Efficiency via Decreasing Drug Protonation.

Nanoscale drug carriers play a crucial role in reducing side effects of chemotherapy drugs. However, the mononuclear phagocyte system (MPS) and the drug protonation after nanoparticles (NPs) burst release still limit the drug delivery efficiency. In this work, a self-disguised Nanospy is designed to overcome this problem.
