Tunable liquid microlenses formed from dynamically re-configurable double emulsions
… control of light propogation on the microscale. Double emulsions formed from immiscible hydrocarbons and fluorocarbons offer a promising platform as reconfigurable micro-optical lenses. These droplet-based lenses can be reconfigured to strongly focusing, nearly transparent, or strongly scattering …

Microfluidic-generated Double Emulsions for Cell Study, Drug Delivery and Particle Therapeutics Fabrication
… of stable, monodispersed and well controlled emulsions to meet specific biological functions are still challenging. First of all, to form more biocompatible W/O/W DE, the microfluidics devices must be patterned with desired surface wettability. W/O emulsion could only form in hydrophobic …

Fabrication of Polymersomes using Microfluidic Devices
… water/organic solvent/water (W/O/W) double emulsion templates. In the former case, the formation of polymersomes occurred at the interface of a flow-focused, copolymer-loaded solvent stream and a selective solvent in a simple microchannel cross junction. Investigations revealed that …

Dynamic and stimuli-responsive multi-phase emulsion droplets for optical components
… sensing, and display technologies. Multi-phase emulsions are micro-scale droplets formed from multiple immiscible material components suspended in a fluid medium. An interesting aspect of these droplets is that by tailoring the chemistry of the surrounding medium it is possible to control the …

Effects of Flow Rate and Droplet Size on Double Emulsion Morphology
… the behavior of water, oil, and gas double emulsions experimentally and through simulation will benefit separation methods that remain inefficient, particularly in froth flotation.</p>

Microfluidic encapsulation of carbon capture materials
… microfluidic device was used to create double emulsions composed of a photocurable polymeric shell that surrounds an aqueous carbon dioxide absorbent core. After droplet formation, the shell was cured using ultraviolet light to form the desired polymer microcapsules. Multiple materials …

Soft matter engineering for cellular bioelectronic interfaces
… flow-cytometric cell-sorting with single-cell double-emulsions(DEs). This platform, known as photosynthetic-organism directed DE-FACS (podDE-FACS), enables rapid in- vestigation of cyanobacteria, microbes with electrogenic capabilities widely used as the biological source of anodic electrons in …

Encapsulation of shock-sensitive materials and their implementation into matrices
… devices to form water-in-oil-in-water (W/O/W) double emulsions. It was determined by optical microscopy and scanning electron microscopy (SEM) that the microcapsules manufactured with the microfluidic device, with diameters between about 200 μm and 300 μm and a shell thickness of about 1.5 μm, …

Design and synthesis of microcapsules using microfluidics for autonomic self-healing in cementitious materials
… microfluidic device was used to produce double emulsions to be selectively photopolymerised to generate a core-shell structure. Subsequently, the physical triggering was assessed by embedding the produced microcapsules in cement paste, fracturing it and observing the cracked surface in …

Investigations of the Role of Triglycerides in Synthetic Colloidal Systems
… of liposomal encapsulation via water/oil/water double emulsions, which involve a drying process to remove the volatile intermediate organic component, and result in high encapsulation efficiencies. The mechanism of their action, however, was previously unexplained. In this work, using …
