Water-in-oil droplet assays are useful for analytical chemistry, enzyme evolution, and single cell analysis, but typically require microfluidics to form the droplets. Here, we describe particle templated emulsification, a microfluidic-free approach to perform droplet assays.

Source: Jose Roberto Moreto, Gustaaf Jacobs and Xiaofeng Liu, Department of Aerospace Engineering, San Diego State University, San Diego, California The delta wing, shown in Figure 1D, is a popular design in high-speed airplanes due to its superb performance in transonic and supersonic flight regimes. This type of wing has a small aspect ratio and high sweep angle, which reduces drag at high subsonic, transonic and supersonic flight regimes. The aspect ratio is defined as the wing span divided...

FAQs
Rapid rotation generates turbulence and shear at the liquid interface. These forces stretch and break the dispersed liquid into smaller droplets, while the surrounding continuous phase receives those droplets. The balance between droplet breakup and subsequent coalescence determines the resulting emulsion structure. This mechanism explains why mixing conditions must be controlled when biological assays require reproducible formulations.
Changing mixing speed or duration changes the energy delivered to the immiscible liquids and can alter droplet size and emulsion stability. Because the appropriate outcome depends on the liquid properties and formulation, speed and time should be treated as controlled experimental variables rather than assumed constants. Consistent settings help produce comparable samples across biological or chemical workflows.
Surfactants and other stabilizers reduce interfacial tension between the immiscible liquids and slow droplet coalescence. This helps the newly formed droplets remain dispersed for longer after mixing. Their inclusion is therefore important when a biological assay, reagent preparation, or encapsulation workflow requires an emulsion with greater stability rather than a short-lived dispersion.
Droplet size and stability depend partly on the properties of the liquids being mixed, as well as on mixing speed, time, and formulation. Consequently, the same vortex settings may not produce identical emulsions with different liquid systems. Recognizing this dependence supports better process control and helps explain variation between formulations used in biological sample or reagent workflows.
A basic workflow combines two immiscible liquid phases in a tube or vessel, includes a surfactant or other stabilizer when the formulation calls for one, and applies vortex motion for a defined period. The resulting emulsion can then be evaluated or used in the intended workflow. Keeping vessel, speed, time, and formulation consistent improves reproducibility.
The setup centers on a tube or vessel containing two immiscible liquids and a vortex-mixing source that rapidly rotates the sample. Depending on the formulation, surfactants or other stabilizers may also be included. These components provide the phases, motion, and interfacial control needed to generate and maintain droplets for biological or chemical work.
In biology, this approach can support sample homogenization, reagent preparation, cell and biomolecule workflows, and controlled emulsion formation for assays or encapsulation. Its value comes from producing dispersed droplets under adjustable mixing conditions. Researchers can select it when they need an emulsion or mixed sample whose droplet size and stability are influenced by controllable process variables.
