title = "Liquid pumping with surface tension-confined microfluidics",
abstract = "This paper presents a unique microscale phenomenon as a possible approach for harnessing surface tension-confined microfluidics, facilitated by the Marangoni effect. Spontaneous flow pulses were generated between droplets with different surface tensions, where the pulsing frequency was a function of the surface tension gradient. We show that the Marangoni effect-driven flow can be used to deliver liquid in small open channels where the boundaries of channels are defined not by solid structures, but by hydrophilic/hydrophobic patterns.",
