Time-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.
