Abstract: 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 (

Abstract: A microfluidic device for use in a serial crystallography apparatus includes a modular 3D-printed nozzle having an inlet, an outlet, and a first snap engagement feature. The microfluidic device further includes a modular 3D-printed fiber holder having an outlet and a second snap engagement feature. The first snap engagement feature is configured to engage the second snap engagement feature to removably couple the nozzle to the fiber holder. The outlet of the fiber holder is aligned with the inlet of the nozzle when the first snap engagement feature is coupled to the second snap engagement feature.
