Small is big: magic microfluidic droplets

roplets of nanoliter and subnanoliter are useful

in a wide range of applications, particularly when

their size is uniform and controllable. Examples include

biochemistry, biomedical engineering, food industry,

pharmaceuticals, and material sciences. One example

of their many fundamental medical applications is the

therapeutic delivery system for delivering site-specific

therapy to targeted organs in the body and as the

carriers for newer therapeutic options. The size, the

size distribution, the generation rate and the effective

manipulation of droplets at a scale of nano, pico, femto

and even atto liters are critical in all these applications.

We make an overview of microfluidic droplet generation

of either passive or active means and report a glass

capillary microfluidic system for synthesizing precisely

controlled monodisperse multiple emulsions and their

applications in engineering materials, nanofluids,

microfibers, embolic particles and colloidosome

systems. Our review of passive approaches focuses on

the characteristics and mechanisms of breakup modes

of droplet generation occurring in microfluidic cross-

flow, co-flow, flow-focusing, and step emulsification

configurations. The review of active approaches covers

the state-of-the-art techniques employing either external

forces from electrical, magnetic and centrifugal fields

or methods of modifying intrinsic properties of flows

or fluids such as velocity, viscosity, interfacial tension,

channel wettability, and fluid density, with a focus on

their implementations and actuation mechanisms. Also

included is the contrast among different approaches of

either passive or active nature.
