Cryopreservation
Cryopreservation is a specialized technique for preserving biological materials (like cells, tissues, or other samples) by cooling them to very low temperatures. Think of it like advanced freezing that labs use to keep important samples viable for long periods. This method is commonly used in medical labs, research facilities, and biotech companies. It's similar to how you might freeze food, but much more precise and scientific, requiring special equipment and careful handling to ensure samples stay usable when thawed.
