Abstract
The effective delivery of protein therapeutics remains a major challenge. Here, the novel nanoplatforms with bovine serum albumin (BSA)‐coated, Dnase‐1‐loaded MnOxnanoflowers are developed (denominated MD@BSA). These MD@BSA nanoplatforms present a highly efficient protein loading and effective delivery Dnase‐I into tumor cells. Under the glutathione (GSH) overexpression environment, MD@BSA is degradable, resulting in Dnase‐1 and Mn2+release for combining protein therapeutics and chemodynamic therapy (CDT), and the GSH‐responsive MR imaging in vivo and vitro that could be used to trace and evaluate the severity of tumor for therapeutic regimen adjustment. This method offers a facile and GSH‐responsive strategy for both delivering proteins and enhanced treatment effect via combined protein‐CDT, which may contribute to the clinical application of protein therapeutics in the future.
