Photomanipulation of a Droplet by the Chromocapillary Effect

Photomanipulation of a Droplet by the Chromocapillary Effect

Ace of hearts: Liquid droplets can be manipulated in a controlled fashion along trajectories of any desired shape (such as a heart, see picture) by using light to create a wavelength‐dependent interfacial tension gradient at a liquid/liquid interface. In this new phenomenon, the “chromocapillary eff...

Zusammenfassung:Ace of hearts: Liquid droplets can be manipulated in a controlled fashion along trajectories of any desired shape (such as a heart, see picture) by using light to create a wavelength‐dependent interfacial tension gradient at a liquid/liquid interface. In this new phenomenon, the “chromocapillary effect”, an interfacial flow generates droplet motion in the direction opposite to the gradient.
