Abstract
Provided are a method for preparing a nano-immune activator, and an article and use thereof. The method includes the following steps: acquiring SF and SS; mixing the SF and the SS according to a set mass ratio, and dissolving in double-distilled water to obtain a water phase; injecting the water phase into an acetone solution as an organic phase to obtain a mixed system; subjecting the mixed system to ultrasonic treatment, and stirring until acetone is completely volatilized; conducting centrifugal treatment, and discarding the supernatant; re-adding double-distilled water into a precipitate, carrying out centrifugal treatment, and collecting the supernatant, and repeating the process for many times; subjecting the obtained supernatant to centrifugal treatment; re-adding double-distilled water into the obtained precipitate, and washing for many times to obtain an SF/SS blending complex; dispersing the SF/SS blending complex in a double-distilled water solution containing trehalose; and freeze-drying the mixed solution.
