摘要：
This disclosure describes, in one aspect, a composition for intracellular delivery of a polypeptide. Generally, the composition includes a substrate that has a surface, a cleavable linker affixed to at least a portion of the surface, and a cargo polypeptide bound to the cleavable linker. In some embodiments, the cargo polypeptide can further include a targeting peptide. In another aspect, this disclosure describes a method for intracellular delivery of a polypeptide. Generally, the method includes administering to a subject any embodiments of the composition summarized above, and cleaving the cleavable linker, thereby releasing the cargo polypeptide from the substrate.
