MS-19: Crystal structures of pharmaceutical and organic compounds from electron diffraction
Invited: Enrico Mugnaioli (Italy), Brent Nannega (USA) | ||
| Session Abstract | ||
|
Many drugs are provided as microcrystalline compounds. Their uptake in the body, the optimisation of their effectivity, and the minimisation of side effects is guided by properties of crystal packing and inter-particle interactions. As a consequence, 3D electron crystallography has attracted increasing attention in the characterisation of pharmaceutical and organic compounds. This microsymposium aims to discuss possibilities and future directions of 3D electron crystallography. For all abstracts of the session as prepared for Acta Crystallographica see PDF in Introduction, or individual abstracts below. | ||
