[0031] The invention provides a simple and efficient preparation method of single-cell bio-based highly hydrophobic micro-powder material. After the single-cell biological cells are repeatedly washed with a dispersant, the single-cell biological cells are activated with an activator to obtain activated Unicellular biological cells; at the same time, Fe can be prepared by a certain method 3 o 4 The nanoparticles are cleaned and modified to realize the combination of the nanoscale particles and the lectin molecules, and obtain the nanoparticles after the biomodification of the lectin molecules. Then, the biomodified nanoparticles of lectin molecules are combined with activated unicellular biological cells, and the Fc 3 o 4 The immobilization of nanoparticles on the surface of single-cell organisms realizes the construction of rough micro-nano structures on the surface of single-cell organisms, and then uses dopamine to modify the surface of the product with octadecylamine to f...
