  • Composition for antifreezing
    Patent number: 11912924
    Abstract: The present invention provides a composition for antifreezing including a gold (Au) nanostructure in which at least a portion thereof is concave, thereby it is possible to increase a survival rate of cells due to having excellent effect of inhibiting ice recrystallization when cryopreservation of the cells, and maintain a texture of food even when using in the freezing of food.
