Electrospray devices are tools for generating aerosols via electrically charged sprays.

The production of aerosols and fine particles finds wide-ranging application in research fields, such as material science, biomedicine, and analytical chemistry. However, traditional aerosol production methods often have limitations when it comes to control over the size and distribution of the particles. Also, these techniques may result in the loss of sample, limiting their efficiency. Current aerosol generation techniques involve mechanical or thermal methods, with shortcomings involving a lack of precise control over particle size and distribution. This lack of precision often results in inconsistent particle size and distribution that potentially impacts the quality of research outcomes or the effectiveness of applications.

Technology Description

Electrospray devices are specialized tools responsible for generating aerosols, or minute particles, via the use of electrically charged sprays. The process employs high voltage to create an electrically charged mist from a liquid sample. The methods of fabricating such devices involve the careful application of electrical engineering and materials science principles for optimum performance. What differentiates electrospray technology is both its versatility and precision. It can be tailored to produce droplets of varying sizes, and the resulting aerosols can be controlled with high precision. This fine control is due to the accurate manipulation of the electrical input and the device’s construction. As a result, applications that require the exact generation of droplets can significantly benefit from electrospray devices.
