The invention belongs to the technical field of pharmaceutical preparations, and particularly relates to an albendazole dispersing agent and a preparation method thereof. The preparation method comprises the following steps: uniformly mixing and dispersing a modified phospholipid compound, a membrane regulator, albendazole and absolute ethyl alcohol, and performing rotary evaporation to obtain the lipid membrane, and adding normal saline into the lipid membrane, mixing and hydrating to obtain the albendazole dispersing agent. Through the technical means of the invention, the albendazole dispersing agent not only has good encapsulation efficiency and storage stability, but also has good in-vitro release performance, and the drug effect can be quickly exerted.

The invention provides a D-A type conjugated polymer based on a CDT electron donating unit and a preparation method and application thereof.PCDT-V-DPP is subjected to side chain modification through Y-axis extension of a donor unit, the complete coplanar characteristic is improved, the dihedral angle between a donor and a receptor of the polymer is increased, an absorption peak is expanded to an NIR window region, and the absorption efficiency is improved. Therefore, the photoacoustic imaging signal intensity is improved. The water-soluble nanoparticles PCDT-V-DPP-coated NPs are prepared by taking the PCDT-V-DPP as a core and a phospholipid compound as a shell, and the photoacoustic performance of the water-soluble nanoparticles PCDT-V-DPP-coated NPs is remarkably superior to that of non-Y-axis conjugate extension PCDT-DPP. According to the invention, by carrying out side chain modification on the CDT unit, compared with a non-completely conjugated plane polymer with the same main chain structure, the polymer has higher brightness and signal-to-noise ratio, PCDT-V-DPP has a narrower band gap and a larger dihedral angle, and non-radiation decay can be effectively improved, so that the photoacoustic imaging performance is improved.
