Microfluidics for Emulsion Synthesis

Emulsions are dispersion of stabilized liquids within a continuous immiscible liquid, and have been widely used in production of pharmaceuticals, cosmetics, foods, electronics, and intermediate products in the synthesis of microcapsules used for protecting actives from chemical degradation or evaporation and for delayed/triggered release.

Microfluidic Production of Emulsions

The microfluidic devices for production of emulsions can be divided into planar (two-dimensional) microfluidic devices and non-planar (three-dimensional) microfluidic devices. Microfluidic device is able to use serial drop makers with alternating wettability to produce multiple emulsions. The wettability of microchannel surfaces can be modified via multiple methods, such as plasma treatment, coating, flow confinement, and salinization, etc.

STEMart can utilize microfluidics techniques to produce different types of emulsion drops to suit a variety of applications.

What We Can Do for You

• Production of simple emulsions, including oil-in-water emulsions and water-in-oil emulsions
• Production of multiple emulsions
  • Production of single-cored emulsion drops, including double, triple, quadruple and quintuple types based on the number of concentric shells surrounding the core
  • Production of multiple-cored emulsion drops, including emulsion drops with controlled number of same or distinct inner drops
  • Production of Janus emulsion drops, including Janus emulsion drops, ternary emulsion drops, emulsion drops with Janus core and emulsion drops with Janus shell
  • Production of multiple-compartment emulsion drops

Advantage of Microfluidic Device in Production of Emulsion Drops

• Ability to fabricate emulsions with complex morphologies
• Ability to control the emulsion drop size at each hierarchical level
• Ability to control the number and the type of inner drops nested inside the outer drop
• Ability to control the internal structure and shape of outer drop
• Ability to independently and individually add different functional ingredients into both the inner and outer drops
