Electrospray: More than just an ionization source

Electrospraying (ES) is a potential‐driven process of liquid atomization, which is employed in the field of analytical chemistry, particularly as an ionization technique for mass spectrometric analyses of biomolecules. In this review, we demonstrate the extraordinary versatility of the electrospray by overviewing the specifics and advanced applications of ES‐based processing of low molecular mass compounds, biomolecules, polymers, nanoparticles,...
