Droplets of nano-/subnano-liter 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, size distribution, generation rate, structure, and manipulation at nano-/subnano-liter scales are critical in all these applications. Prof. Wang will show the big impact of small microfluidic droplets with an overview of their generation, manipulation, and application. Their precision generation counts on system geometries, fluid properties and flow rates; their effective manipulation is magically enabled with the phase separation, microfluidic channels, droplet overlay, and fiber or light touch; their beautiful application includes embolic particles, smart colloidosome drug delivery, super thermal conductors, and super anti-pathogenic coatings.
