Advanced Nanomaterials-Assisted Cell Cryopreservation: A Mini Review

Area of Science:

• Biomaterials Science
• Cell Biology
• Nanotechnology

Background:

• Cell cryopreservation is crucial for cell transport and storage, requiring cryoprotective agents (CPAs) to prevent freeze-thaw damage.
• Traditional organic solvent CPAs exhibit significant cytotoxicity and necessitate extensive post-thaw washing.
• There is a growing need for advanced CPAs with reduced toxicity and improved efficiency.

Purpose of the Study:

• To review the application of advanced nanomaterials in cell cryopreservation.
• To highlight novel nanomaterials as alternatives to conventional cryoprotectants.
• To provide insights into the potential of nanomaterials for improved cryopreservation outcomes.

Main Methods:

• Review of current literature on nanomaterials used in cell cryopreservation.
• Categorization of nanomaterials into organic/inorganic nanoCPAs and nanodelivery systems.
• Analysis of the efficacy and advantages of these nanomaterials compared to traditional CPAs.

Main Results:

• Nanomaterials can act as effective cryoprotectants or delivery vehicles for less toxic CPAs.
• Emerging nanomaterials demonstrate potential for lower cytotoxicity and simplified post-thaw processing.
• These advanced materials offer comparable or superior cryoprotective effects to conventional agents.

Conclusions:

• Nanomaterials represent a significant advancement in cell cryopreservation technology.
• Their application promises to overcome the limitations of traditional cryoprotectants, enhancing cell viability.
• This field holds great potential for future developments in cell-based therapies and research.
