Just out: Minimized sample consumption for time-resolved serial crystallography applied to the redox cycle of human NQO1

Minimized sample consumption for time-resolved serial crystallography applied to the redox cycle of human NQO1
Communications Chemistry, Published online: 29 January 2026; doi:10.1038/s42004-026-01908-9Time-resolved serial femtosecond crystallography at X-ray free-electron lasers is a powerful approach for studying macromolecular dynamics, but its widespread use is limited by high sample consumption. Here, the authors introduce a segmented-droplet mix-and-inject strategy at the European XFEL that reduces sample consumption by up to 97% while preserving the data quality required for time-resolved structural studies of the enzyme NQO1.
