In order to better understand the mechanism by which nanoparticles change the nature of the cryoprotectant solution and further utilize nanotechnology to improve the preservation effect at low temperatures, this paper introduces the rise and development of nanoscale cryoprotectants; discusses the effects of adding nano-low temperature The protective agent can improve the thermal conductivity of the solution, change the rheological properties, increase the viscosity, lower the degree of supercooling and change the vitrification property. The application and future development prospects of the nanostructured cryoprotectants in low temperature organisms are summarized.
