Why a lyophilised solid behaves the way it does

Published 24 October 2026 · REVIVE LAB UAE Research Desk · 5 min read
Lyophilisation freezes a solution and removes water by sublimation too fast for molecules to arrange into a crystal lattice, leaving a disordered, porous, glassy solid. Amorphous solids dissolve faster than crystals, take up water more readily, and have higher molecular mobility, which makes them less stable than a crystalline form of the same compound would be. The lyophilised GHK-Cu cake is such a solid.

How the solid forms

Ice crystals grow as the solution freezes, excluding solutes into the spaces between. When the ice sublimes, those spaces become pores and the solute is left as a disordered matrix. There is no time or mobility for crystallisation, so the result is a glass.

The porous structure is what gives a cake its appearance and its large surface area.

Consequences

Fast dissolution, because water penetrates the pores and there is no lattice to break. Hygroscopicity, because the surface is large and the structure open. Higher mobility than a crystal, so degradation reactions in the solid proceed faster than they would in crystalline material — though far slower than in solution.

These are the trade-offs of the format, and the reasons for cold, dry storage.

For the copper complex

The amorphous state preserves the coordination as it was in solution. A crystalline form would have a defined geometry; the glass has the solution geometry frozen in. Dissolving the cake returns the complex to solution unchanged.
