Publication number: US20220023813A1
Application number: 17/450,731

Fabrication of functional polymer-based particles by crosslinking UV-curable polymer drops in mid-air and collecting crosslinked particles in a solid container, a liquid suspension, or an air flow. The particles can contain different phases in the form or layered structures that contain one to multiple cores, or structures that are blended with dissolved or emulsified smaller domains. A curing system produces ultraviolet rays that are directed onto the particles in the jet stream from one side. A reflector positioned on other side of the jet stream reflects the ultraviolet rays back onto the particles in the jet stream.

Application number: 17/464,135

The invention generally relates to systems including nanoelectrospray ionization emitters in a movable array format in which the emitters can be loaded, singly or simultaneously, through their narrow ends using a novel dip and go method based on capillary action, taking up sample from an array. The sample solutions in each emitter can be electrophoretically cleaned, singly or simultaneously, by creating an inductive electric field that moves interfering ions away from the narrow end of the capillary. Subsequent to cleaning, the emitters are supplied with an inductive electric field that causes electrospray into a mass spectrometer allowing mass analysis of the contents of the emitter.
