DOUBLE EMULSIONS. Double emulsions are drops inside of drops and they are useful in applications like drug delivery, cosmetics and for performing chemical reactions inside of drops. Typically multi-component double emulsions are produced using a multi-step process but here, in a new microfluidic technique, we are able to generate them in a single step. Two small water droplets, dyed different colors, are generated at nozzles of a dual bore injection capillary while oil flows down the outside of the injection capillary to capture the droplets. The encapsulated droplets then flow as a single multi-component double emulsion to the right in the outer carrier fluid to exit the microfluidic device. By controlling the flow rates of the fluids, the number and size of the encapsulated drops can be tuned. Finally, the spacing of the channels in the injection capillary is critical to prevent the inner droplets from merging with one another before encapsulation. (Video credit: L. L. A. Adams.)
LYSOSOME CRYSTAL GROWTH. Lysozymes are a type of enzyme found in tears, saliva, human milk and mucus. This movie was taken using a microscope with polarized light by the Newcastle Structural Biology Lab.
