Degradable polymers were synthesized that self-assemble with nucleic acids, proteins, hydrophobic drugs, and other small molecules to form particles that are effective for delivery into a cell, tissue and/or organism either in vitro or in vivo. The presently disclosed polymers demonstrate differential cell-type specificity, an ability to promote endosomal escape to protect the cargos from degradation and enhance delivery to the cytoplasm, and/or bioreducibility, which enables triggered intracellular drug release to be tuned to promote optimal delivery to the target cell type. The presently disclosed materials may be used to treat a wide variety of conditions or diseases, such as cancer, cardiovascular diseases, infectious diseases, and ophthalmic diseases.
