Precise and effective control of droplet generation is critical for applications of droplet microfluidics ranging from materials synthesis to lab-on-a-chip systems. This application note focuses on microfluidic flow focusing droplet generation, where additional energy input promotes insta...
Flow focusing is a key operation in microfluidics, involving applications that range from flow cytometry to nanoprecipitation on chips. Attaining a rational control of the width of the focused stream has been a concern since the development of the technique. The available analytical models effectively...

Flow focusing systems are widely used for the continuous generation of droplets in microfluidics1,2,3,4. The size, gap and generation rate of droplets can be controlled by varying the viscosity, interfacial tension and flow rates of incoming core and sheath flows5. The surface properties of the...
The 3D focusing in our approach is similar to that observed in some glass capillary-based microfluidic systems. However, embedding a microneedle in a PDMS microchannel, as seen in this manuscript, has several advantages. Namely, the tapered glass capillaries used in microfluidics are fragile, and ...
The most common geometries used to generate droplets in microfluidic devices are: Cross flowing (T-junction,) flow focusing and co-flowing.
