    Abstract: The present invention discloses an SERS substrate of a metal-modified semiconductor-based bionic compound eye bowl structure and a construction method, and belongs to the technical field of nano materials. The present invention is based on a multi-time interface self-assembly method. Firstly, a small ball template is constructed by using a gas-liquid interface assembly process. Then, a semiconductor bowl structure array is induced to be formed by the template by using a solid-liquid interface assembly process. Next, a semiconductor bowl is assembled to a surface of a pyramid-shaped cone to form a bionic compound eye structure by using a transfer process. Finally, a surface of the bionic compound eye structure is modified with a layer of uniformly distributed metal particles by a physical deposition method or a chemical deposition method, thereby forming the SERS substrate of the metal-modified semiconductor-based bionic compound eye bowl structure.

  • Patent number: 10933028
    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 zwitterionic polymer is crosslinked by cysteamine, producing pH/reduction responsive polyamino acid zwitterionic nanoparticles after purification. 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.
