Query: Surface tension effects on immersed electrosprays   Electrosprays are a powerful technique to generate charged
micro/nanodroplets. In the last century, the technique received extensive study
and successful applications, including a Nobel price in Chemistry. However,
nowadays its use in microfluidic devices is still limited mainly due to a lack
of knowledge of the phenomenon when the dispersing fluid is immersed in another
inmiscible liquid. The "immersed electrosprays" share almost identical
properties as their counterparts in air. Things however change when surface
active agents are added to the host liquid, which are normally used in
lab-on-chip applications to stabilize the generated emulsions. In this work, we
review the main properties of the immersed electrosprays in liquid baths with
no surfactant, and we methodically study the behavior of the system for
increasing surfactant concentrations. The different regimes found are then
analyzed and compared with both classical and more recent experimental,
theoretical and numerical studies. A very rich phenomenology is found when the
surface tension is allowed to vary in the system. More concretely, the lower
states of electrification achieved with the reduced surface tension regimes
might be of interest in biological or biomedical applications in which the free
charge is normally hazardous for the encapsulated entities.
