When miniaturizing fluidic circuitry, the solid walls of the fluid channels become increasingly
important because they limit the flow rates achievable for a given pressure drop, and they …

Abstract'Lab-on-a-chip'systems resemble factories with permanently rigged pipes, but their
prefabricated microchannels could have problems in delivering materials such as …

It has long been known that a continuous liquid film can spontaneously form into droplets
that move freely over surfaces without application of an obvious external force. For example …

Microscopic fluidic devices, ranging from surgical endoscopes and microelectromechanical
systems to the commercial 'lab-on-a-chip'(ref.), allow chemical analysis and synthesis on …

Controlling the wetting behaviour of liquids on surfaces is important for a variety of industrial
applications such as water-repellent coatings and lubrication. Liquid behaviour on a surface …

Microfluidics have enabled notable advances in molecular biology,, synthetic chemistry,,
diagnostics, and tissue engineering. However, there has long been a critical need in the …

Microfluidics has great potential, but the complexity of fabricating and operating devices has
limited its use. Here we describe a method—Freestyle Fluidics—that overcomes many key …

Numerous processes from offset printing to painting depend on the rapid spreading of water
droplets on solid surfaces. On page 633 of this issue, Daniel et al.(1) report on the …

The ability to manipulate droplets on a substrate using electric signals—known as digital
microfluidics—is used in optical,, biomedical,, thermal and electronic applications and has …

The microfabrication technologies of the semiconductor industry have made it possible to
integrate increasingly complex electronic and mechanical functions, providing us with ever …
