WebApr 29, 2024 · 1.5.2. Crystallization of salt or macromolecules. For a droplet of salt or macromolecular solution, evaporation results in the oversaturation of solute, thus leading to its crystallization. It is often observed that the salt crystals as well as protein crystals grow in the form of faceted phase ( Fig. 5 a).
