Novel Antifreeze Materials for Gamete and Embryo Cryopreservation Applications
Cryopreservation of gametes and embryos is the freezing of gametes and embryos under ultra-low temperature conditions to achieve the purpose of long-term preservation.Cryopreservation technology plays an important role in germplasm conservation,preservation and improvement of animal genes.Due to the toxicity of traditional cryoprotectants,researchers are currently working on the development of new antifreeze materials with low toxicity and significant antifreeze effect,such as antifreeze proteins,nanomaterials and polymers.This paper briefly describes the principles and problems of cryopreservation technology,summarizes the antifreeze mechanism and application progress of three new antifreeze materials,and provides a new perspective for cryopreservation of gametes and embryos from the perspective of materials engineering,aiming to expand new ideas for the development of more novel materials.
