Developing improved medical countermeasures against chemical warfare agents (nerve agents) is urgently needed but time-consuming and costly. Here we introduce a robot-assisted liquid handling system with warming, cooling and incubating facilities to screen the detoxifying properties of biological and chemical

A wide range of organophosphorus nerve agents, including Soman, Sarin, and Tabun is efficiently hydrolyzed by the phosphotriesterase enzyme diisopropyl fluorophosphatase (DFPase) from Loligo vulgaris. To date, the lack of available inhibitors of DFPase has limited studies on its mechanism.

X-ray and neutron crystallographic techniques provide complementary information on the structure and function of biological macromolecules. X-ray and neutron (XN) crystallographic data have been combined in a joint structure-refinement procedure that has been developed using recent advances in modern computational
