Studies from Arizona State University Reveal New Findings on Science and Technology (Liquid sample delivery techniques for serial femtosecond crystallography)

By a News Reporter-Staff News Editor at Science Letter -- Fresh data on Science are presented in a new report. According to news reporting originating in Tempe, Arizona, by NewsRx editors, the research stated, "X-ray free-electron lasers overcome the problem of radiation damage in protein crystallography and allow structure determination from micro-and nanocrystals at room temperature. To ensure that consecutive X-ray pulses do not probe previously exposed crystals, the sample needs to be replaced with the X-ray repetition rate, which ranges from 120 Hz at warm linac-based free-electron lasers to 1 MHz at superconducting linacs."

The news reporters obtained a quote from the research from Arizona State University, "Liquid injectors are therefore an essential part of a serial femtosecond crystallography experiment at an X-ray free-electron laser. Here, we compare different techniques of injecting microcrystals in solution into the pulsed X-ray beam in vacuum."

According to the news reporters, the research concluded: "Sample waste due to mismatch of the liquid flow rate to the X-ray repetition rate can be addressed through various techniques."
