The current vitrification-based oocyte cryopreservation relies on inherently cytotoxic high-concentration cryoprotective agents (CPAs), leading to suboptimal post-thaw survival rates and diminished developmental competence. To address this, we developed a series of highly biocompatible amino-functionalized iron-based metal-organic frameworks (Fe-MOFs) via facile hydrothermal method synergistically suppress ice crystallization minimize the reliance toxic CPAs. Among synthesized materials, 2NH2-MIL88(Fe) demonstrated exceptional ice-inhibition performance, reducing crystal size 16.78% that observed in pure water, significantly outperforming its nonaminated counterpart MIL88(Fe) monoaminated NH2-MIL88(Fe). Notably, exhibited an unprecedented intrinsic photothermal response without requiring photosensitizer modification, achieving rapid temperature elevation from 25 86.6 °C under 808 nm laser irradiation (1 W/cm2, 1 min). When applied mouse cryopreservation, this dual-functional amino-MOF enabled complete elimination dimethyl sulfoxide (DMSO) CPAs while maintaining rate 95.1%. Our findings establish dual correlation between amino group density both ice-growth suppression efficiency revealing synergistic mechanism for enhancement. This structure-function relationship provides critical insights rational design next-generation nano-CPAs.

Cryopreservation techniques have been widely used, especially in biomedical applications and preservation of germplasm resources. Ideally, biological materials would maintain functional integrity as well a normal structure can be recovered when needed. However, this tool does not work all the time. Ice formation growth are key challenges. The other major reason is that cryoprotective agents (CPAs) currently used do meet these needs always accompanied by their cytotoxicity. A comprehensive synergistic approach focuses on overall frozen system crucial for evolution cryopreservation methods. In review, we first summarize fundamental damage mechanisms during cryopreservation, common cryoprotectants limitations. Next, discuss interact with ice to improve outcomes. We evaluated natural synthetic materials, including sugars polymers, AFPs mimics, nucleators, hydrogels. addition, biochemical regulation, which enhances tolerance biosamples cryopreservation-induced stresses, was also mentioned. Nanotechnology, cell encapsulation, cryomesh, isochoric freezing, such scalable approaches, further discussed cryopreservation. Finally, future research directions field efficient proposed. emphasized need multidisciplinary progress address combination cryobiology technologies, biology, nanotechnology, microfluidics, 3D bioprinting, highlighted.
