Journal ArticleDOI
Creating, transporting, cutting, and merging liquid droplets by electrowetting-based actuation for digital microfluidic circuits
TL;DR: In this paper, the authors report the completion of four fundamental fluidic operations considered essential to build digital microfluidic circuits, which can be used for lab-on-a-chip or micro total analysis system (/spl mu/TAS): 1) creating, 2) transporting, 3) cutting, and 4) merging liquid droplets, all by electrowetting.
Journal ArticleDOI
Turning a surface superrepellent even to completely wetting liquids
Tingyi Leo Liu,Chang-Jin Kim +1 more
TL;DR: In this article, the authors showed that roughness alone, if made of a specific doubly reentrant structure that enables very low liquid-solid contact fraction, can render the surface of any material superrepellent.
Journal ArticleDOI
Large Slip of Aqueous Liquid Flow over a Nanoengineered Superhydrophobic Surface
Chang-Hwan Choi,Chang-Jin Kim +1 more
TL;DR: A nanostructured superhydrophobic surface is engineered that minimizes the liquid-solid contact area so that the liquid flows predominantly over a layer of air.
Journal ArticleDOI
Electrowetting and electrowetting-on-dielectric for microscale liquid handling
TL;DR: Electrowetting and electrowetting-on-dielectric (EWOD) as discussed by the authors can control the wettability of liquids on solid surfaces using electric potential, which can be applied to microfluidic devices.
Journal ArticleDOI
Characterization of Nontoxic Liquid-Metal Alloy Galinstan for Applications in Microdevices
TL;DR: In this paper, the interfacial properties of Galinstan, a nontoxic liquid-metal alloy, to help replace mercury in miniature devices, were investigated in a nitrogen-filled glove box.
