英文摘要：

In order to have a better understanding of the mechanism of nanoparticles to change the properties ofcryoprotectants,and to further utilize nanotechnology to improve the effect of cryopreservation,the rise anddevelopment progress of nano-cryoprotectants was introduced.Nanoparticles could promote thermal conductivity,change rheological properties,increase the viscosity,reduce supercooling and alter vitrification properties in theprocess of cryopreservation.It summed up the application of nano-cryoprotectants in cryobiology and theforeground of cryopreservation.
