Cryoprotective agents (CPAs) protect biological materials during freezing and thawing by reducing ice formation, osmotic injury, and membrane damage. This article explains CPA types, mechanisms, toxicity, and their role in modern cryopreservation.

Cryopreservation is a vital technology that preserves biological materials at ultra‑low temperatures, supporting medicine, research, agriculture, biotechnology, and wildlife conservation. This article explores its diverse applications and growing importance in science and global biodiversity protection.
