How To Optimize Lyophilization with Thermal Analysis

Lyophilization, also called freeze-drying, is the process of removing water from a sample, often for preservation. Lyophilization involves the sublimation of a sample’s water content, usually through a rapid freezing process. Freezing materials quickly helps avoid the destruction of the cell walls in the sample from the formation of large ice crystals.

Rheology of Hydrogels

Hydrogels are three-dimensional porous strctures that can absorb large amounts of water. They can be made up of polymers, protein, peptides, colloids, surfactants, or lipids.1 Hydrogels’ ability to uptake large amounts of water is useful for many biological applications, including drug delivery and tissue engineering. Since a hydrogels’ properties change as it absorbs water, scientists must accurately characterize its behavior at different saturation amounts and in varying conditions.
