摘要: 我国地方品种通过不断地进化与演变已经能够很好地适应当地的农业生态环境,虽然在一些生产性能方面表现较差,但其仍具有环境适应性高、耐粗饲、抗病能力强等诸多优点,对杂交改良培育新品种而言有着不可或缺的重要作用。近些年来,随着人们对经济效益及生产效率的盲目追求,国外优良品种被大量引入,导致许多国内地方品种逐步走下了历史舞台,被国外优良品种所取代,使得国内地方品种资源受到了严重的威胁。随着低温生物学的发展,利用冷冻保存的生物样本库对种质资源进行保种育种得到了广泛推广。但在冷冻保存动物种质资源过程中,由于氧化应激使得种质资源长期保存受到制约。有人研究一些抗氧化化合物的添加可以有效降低氧化应激从而防止细胞冻伤,但是传统的抗氧化化合生物利用度低,临床应用效果差。纳米粒子作为一种新兴材料,由于其独特的物理结构,可以提高生物利用度,使其被广泛应用于辅助生殖技术、生物医学、生物药学、化妆品等领域。因此,本综述重在回顾纳米粒子在冷冻保存中的新兴应用的效果,总结了一些最有前途的研究进展,并全面讨论了纳米粒子在冷冻保存动物种质资源中的局限性和优势,从而为动物种质资源冷冻保存提供新的方案。

Abstract: Chinese local livestock breeds, through continuous evolution and adaptation, have become well-suited to their local agricultural ecological environments. Although they may exhibit lower performance in certain production traits, they possess numerous advantages such as high environmental adaptability, tolerance to coarse feeds, and strong disease resistance. These qualities make them indispensable for crossbreeding and the development of new breeds. In recent years, driven solely by the pursuit of economic efficiency and productivity, superior foreign breeds have been extensively introduced. This has led to the gradual phasing out of many domestic local breeds, replaced by their foreign counterparts, posing severe threats to the conservation of domestic local breed resources. With the advancement of cryobiology, the use of biobanks for cryopreservation has become a widely adopted method for conserving germplasm resources. However, during the cryopreservation of animal germplasm, oxidative stress significantly constrains their long-term preservation. Studies have shown that adding certain antioxidant compounds can effectively mitigate oxidative stress and prevent cryodamage to cells. However, traditional antioxidants suffer from low bioavailability and poor clinical efficacy. Nanoparticles (NPs), as an emerging material, possess unique physical structures that enhance bioavailability. This has led to their widespread application in fields such as assisted reproductive technologies, biomedicine, biopharmaceutics, and cosmetics. Therefore, this review focuses on the emerging applications and efficacy of nanoparticles in cryopreservation. It summarizes some of the most promising research progress and comprehensively discusses both the limitations and advantages of using nanoparticles for the cryopreservation of animal germplasm resources. The aim is to provide novel solutions for the cryopreservation of animal genetic resources.

Key words: nanoparticles, germplasm resources, cryopreservation, mechanism of action, application effect
