a Schematic representation of a fixed-target sample delivery system with an array of crystals positioned on a solid support. The solid support is mounted on a stage to position a specific crystal in the path of the X-ray beam to collect diffraction data on the detector. b Si-based fixed-target device developed by Mueller et al.89 where crystal slurry was loaded with a pipette tip, and the excess mother liquor was removed from the back of the chip (reproduced with permission from ref. 89).
