Knowing about crystal formation of organic compounds is knowing about pathways to improve the patient’s life. The crystal shape and size impact drug aspects such as flowability, compatibility, dissolution, and absorption rate. Membranes play a key role in controlling the production of heat-sensitive compounds: first, by controlling the mass transfer of the antisolvent into the solution, increasing gradually supersaturation necessary to form solid crystals; second, it provides a substrate to heterogeneous crystallization. This image, taken using SEM, shows the membrane’s support in controlling crystallization analogous to the Dragon's support of Khaleesi (in reference to the characters from Game of Thrones).
