Freeze-drying, also known as lyophilization, is a widely used technique for preserving biological samples. This paper explores the effects of freeze-drying on the preservation of biological samples, with a focus on Lia Lin's contributions to cryopreservation techniques. We discuss the principles of freeze-drying, its applications in various fields, and the challenges associated with the technique. We also examine Lia Lin's work on optimizing freeze-drying protocols for preserving biological samples and its impact on the field.
