Single Emulsion Synthesis Services

Inquiry

Microfluidics is capable of generating monodisperse, single emulsion droplets with precise control and operations. It has been a powerful tool for fabricating complex systems (microparticles, microcapsules, microgels) with uniform size, narrow size distribution and desired properties, showing great potential in cosmetics, foods and pharmaceuticals applications. As a leader in microfluidic chip development, Creative Biolabs is dedicated to establishing the most exquisite microfluidic platform and providing one-stop microfluidic solutions for the formation of single emulsions with high throughput and precision.

Introduction of Single Emulsions

As the simplest form of emulsions, single emulsions consist of a liquid droplet dispersed in a different fluid and are often stabilized with surfactants. The basic forms of single emulsions include water-in-oil (W/O) and oil-in-water (O/W). They are frequently used as vessels for tissue engineering, biosensing, drug delivery and drug release. Especially, single emulsions can function as a compartment to conduct biochemical reactions in small volumes or to perform screening assays at high throughputs while consuming minimal sample volumes. For instance, single-cell emulsion techniques employ W/O single emulsions in which a large aqueous droplet containing cells and reagents is surrounded by oil.

Microfluidics-based Single Emulsions Formation

The applications of single emulsions depend on their properties which correlate with their size, structure, composition and configuration. Therefore, it is essential to fabricate single emulsions in a controlled manner to improve their pharmaceutical capability and reliability for biological studies. In contrary to continuous flow systems, microfluidics deals with discrete droplets to produce single emulsions with precise control of their volume and composition, restricted dispersion and limited cross-contamination. The high monodisperse single emulsions present narrow size distribution (less than 1% size variation) and improved encapsulation efficiency.

Droplet Microfluidic Device for Single Emulsions Formation

Droplet microfluidics is one of the most effective techniques for the tailored fabrication of single emulsions. It offers exquisite control over the flows of multiple fluids in microscale, enabling the fabrication of advanced microparticles with precisely tunable structures and compositions in a high throughput manner.

Featured Services at Creative Biolabs

With years of experience and advanced microfluidic platforms, Creative Biolabs pioneers the use of microfluidic devices for single emulsions control and analysis. Our microfluidic chip can precisely control the size of droplets either by passive ways through tuning the geometry of microfluidic devices, the properties of two liquid phases (viscosity and interfacial tension) and the operating parameters (flow rates of two phases, pressure, etc.) or by active methods through electrical forces, temperature, magnetic force, optical manipulation and acoustic force. The size variation is usually less than 1% and the encapsulation efficiency is up to 100%.
