Abstract: The invention discloses a preparation method of pH/reduction responsive polyamino acid zwitterionic nanoparticles, which belongs to the technical field of polymer synthesis and biomedical materials. In the invention aliphatic amines are used to initiate ring-opening polymerization of ?-benzyl-L-glutamate-N-carboxylic anhydride, and the obtained poly(?-benzyl-L-glutamate) reacts with L-lysine to form azwitterionic polymer.

The nanoparticles are pH responsive and resistant to non-specific protein adsorption. Because cysteamine contains disulfide bonds, the nanoparticles have sensitive reductive responsiveness and can load anticancer drugs for controlled release at the target site of cancer.
