A Brief History of Drop Formation
Surface-tension-related phenomena have fascinated researchers for a long time, and the mathematical description pioneered by Young and Laplace opened the door to their systematic study. The time scale on which surface-tension-driven motion takes place is usually quite short, making experimental investigation quite demanding. Accordingly, most theoretical and experimental work has focused on sta...
متن کاملAir-bubble-triggered drop formation in microfluidics.
In microfluidic devices, droplets are normally formed using T-junction or flow focus mechanisms. While both afford a high degree of control over drop formation, they are limited in maximum production rate by the jetting transition. Here, we introduce a new drop formation mechanism that is not limited by jetting, allowing much faster drop production.
متن کاملValve-based flow focusing for drop formation
Picoliter drops made in microfluidic devices can serve as individual compartments for chemical reactions and can be processed at kilohertz rates with high precision. This combination of speed and containment is very useful for highthroughput screening, for discovering novel drugs, for sorting analytes and worms, and for directed evolution of enzymes and cells. For applications in microfluidics,...
متن کاملManipulating Drop Formation in Piezo Acoustic Inkjet
Inkjet developments move towards higher productivity and quality, requiring adjustable small droplet sizes fired at high repetition rates. Normally, maximum jetting efficiency is achieved by tuning the slopes of the driving waveform to the travel times of acoustic waves inside the channel. Important parameters are channel length, compliance of channel cross-section (through its impact on the ef...
متن کاملEfficient encapsulation with plug-triggered drop formation.
Monodisperse microscale drops formed with microfluidic devices are useful for encapsulating cells, microgel particles, or even additional drops. These techniques are thus useful for applications ranging from high-throughput biology to monodisperse particle and capsule synthesis, which require encapsulation of such objects. However, it is challenging to efficiently encapsulate the objects in all...
