Abstract: The present disclosure relates to a method for preparing and characterizing zein-fucoidan conjugated nanoliposomes for phytol encapsulation. The method of preparation includes a preparation of zein-fucoidan nanoparticles. This includes (i). dissolving zein in a 75% ethanol solution, and preparing a fucoidan solution by mixing 40 mL of ultrapure water with 200 mg of fucoidan, (ii). removing ethanol from a resulting mixture, and (iii) eliminating insoluble substances to collect the zein-fucoidan nanoparticles. The method further includes. preparation of nanoliposomes and preparation of biopolymer conjugated nanoliposomes. The zein-fucoidan nanoparticles and nanoliposomes are combined in a specific ratio to prepare the biopolymer conjugated nanoliposomes. In the present disclosure, Zein and fucoidan are utilized as a composite biopolymer to modify nanoliposomes loaded with phytol, thereby enhancing the performance of phytol nanoparticles.

Abstract: A method includes: obtaining a push content request from an object; determining a push content set according to the push content request; detecting historical behavior feature data of the object for a push content in response to a behavior feature of the object for the push content satisfying a preset negative behavior condition; performing content-based matching for the push content set based on the historical behavior feature data to obtain a target push content set of the object; performing content sorting of the push content set and performing content-based matching of the push content of the object to obtain a target push content set of the object; and determining a target push content of the object from the target push content set, and transmitting the target push content to the object.
