title: Motion of liquids on surfaces.
abstract: The macroscopic manipulation of liquids is a core component to the development of microfluidic devices. Although the Marangoni effect has been described for well over a century, actively tuning such surface tension effects is a more recent achievement. This Highlight compares recently reported electro- and photochemical methods in which this liquid manipulation has occurred. One such method, electrocapillarity as utilised by Prins et al., is shown in the picture.
