3D printed microfluidic mixers and nozzles for crystallography
A 3D printed hybrid nozzle device combining a microfluidic mixer with a liquid jet injector that addresses the bottleneck of investigating substrate-initiated biological reaction paths employing serial crystallography with XFELs. The hybrid nozzle provides for injecting aqueous protein crystal jets after fast mixing (<5 ms), reaching reaction time points (e.g., about 10 ms to about 150 ms) suitable to resolve enzyme kinetics.
Device for hosting a probe solution of molecules in a plurality of independent cells
A device to host a crystallization medium, such as a solution, for crystal growth and a system for X-ray diffraction experiments to determine the atomic structure of crystals. A plurality of cells have a well, a sample holder placed in the well. The solution is hosted in the sample holder between thin-plates or one thin-plate. A cap seals an opening to the cell and each sample holder can be extracted independently from each well. A system for automated X-ray diffraction experiments for small crystals in the sample holder extracted from the wells utilizes an ultrasonic acoustic levitator to determine the crystal structure at atomic resolution. X-ray diffraction images are generated by scanning the X-ray beam over the levitated sample holder along a spiral trajectory by rotating the sample holder and moving in the direction perpendicular to the X-ray beam and the rotation axis at the same time.
DEVICE FOR TUNING MICROFLUIDIC DROPLET FREQUENCY AND SYNCHRONIZING PHASE FOR SERIAL FEMTOSECOND CRYSTALLOGRAPHY
Methods and systems are provided for serial femtosecond crystallography for reducing the vast amount of waste of injected crystals practiced with traditional continuous flow injections. A micrometer-scale 3-D printed water-in-oil droplet generator device includes an oil phase inlet channel, an aqueous phase inlet channel, a droplet flow outlet channel, and two embedded non-contact electrodes. The inlet and outlet channels are connected internally at a junction. The electrodes comprise gallium metal injected within the 3-D printed device. Voltage across the electrodes generates water-in-oil droplets, determines a rate for a series of droplets, or triggers a phase shift in the droplets. An external trigger generates the droplets based on the frequency of an XFEL utilized in droplet detection, thereby synchronizing a series of droplets with x-ray pulses for efficient crystal detection. The generated droplets can be coupled to an SFX with XFEL experiment compatible with common liquid injector such as a GDVN.
