Disclosed are a liquid supramolecular self-recognition system of low-pH azelaic acid, and a preparation method therefor and application thereof. The preparation method for the ternary liquid supramolecular self-recognition system of low-pH azelaic acid/succinic acid/panthenol includes the following steps: mixing and heating azelaic acid, succinic acid, and panthenol in a molar ratio of 1:0.5:1-1:10:10 in a sealed container to obtain a mixture and heated at 60-120° C. for more than 1-24 hours, and cooling down the mixture to room temperature after the heating is completed to obtain the liquid supramolecular self-recognition system of low-pH azelaic acid. The preparation method is green and simple, and the resulting supramolecular self-recognition system can effectively improve the solubility of azelaic acid, and have excellent stability without precipitation. In addition, the supramolecular self-recognition system for the azelaic acid/succinic acid/panthenol prepared in the present disclosure is in a liquid form, and can be directly applied to subsequent formulations without special treatment.

Liquid supramolecular self-recognition system of low-pH azelaic acid, and preparation method therefor and application thereof

The present invention discloses a bionic SERS substrate of a metal-based compound eye bowl structure, a construction method and application. The bionic SERS substrate of the metal-based compound eye bowl structure of the present invention consists of a metal bowl and a cone-shaped structure substrate in an ordered hierarchy manner. The metal bowl is of a continuously and closely arranged single-layer bowl structure. A height of the metal bowl is 0.01-10 &#x3bc;m, and a bowl opening diameter is 0.01-10 &#x3bc;m. A cone is a micron pyramid cone, and a height of the micron pyramid cone is 1-100 &#x3bc;m. The present invention assembles the metal bowl on a surface of the substrate of the micron pyramid cone structure with great fluctuation by a solid-liquid interface chemical reduction method and a small ball template method, and further constructs a 3D SERS substrate with a bionic compound eye structure.

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.
