Methods, devices, and systems for performing nebulization of a sample from a fluid channel of a microfluidic device are described. The systems or devices disclosed herein may comprise microfluidic devices that comprise a gas channel used for nebulization of the sample at a fluid outlet of the microfluidic device. In some instances, the disclosed devices may be designed to perform isoelectric focusing followed by further characterization of the separated analytes using electrospray ionization coupled with nebulization to introduce the samples into a mass spectrometer. The disclosed methods, devices, and systems provide for fast, accurate separation and characterization of protein analyte mixtures or other biological molecules by isoelectric point.

Devices and methods are provided to apply thin layers of antimicrobial coatings onto a wide variety of substrates and articles. The methods can be performed at moderate temperatures and pressures, allowing for the coating of sensitive substrates and articles.

A chamber (1) and an air conduit (7) connecting a liquid surface retaining hole (5) with an air hole (6) for supplying air from the outside of an electrostatic atomizer (50) to the chamber (1) are provided. When the liquid surface retaining hole (5) is blocked, the liquid supply from a liquid supplying section (3) to the chamber (1) will be stopped. The air conduit (7) has bent sections (8), and a space (10) for holding the liquid is formed in the air conduit (7).

An electrostatic fluid delivery system is configured to deliver fluid, such as a disinfectant fluid, onto a surface by electrically charging the fluid and forming the fluid into a mist, fog, plume, or spray that can be directed onto a surface, such as a surface to be cleaned. The system atomizes the fluid using a high-pressure fluid stream and passes the fluid through an electrode of a nozzle assembly to charge droplets of the atomized fluid.

Provided in certain embodiments herein are alternating current electrospray systems and processes for manufacturing depositions, such as thin layer depositions. In some embodiments, processes and systems provided herein are suitable for and configured to manufacture uniform depositions, such as having uniform thickness.
