Confocal slice of colloids crystallizing in index and density matched high dielectric solvents exhibiting hard sphere behavior: Tom Kodger.

This image is an optical micrograph of a colloidal crystal composed of monodisperse 3 micrometer-diameter latex particles assembled by solvent evaporation on a glass slide. The "flower" is an optical illusion, probably due to the presence of a vacancy in the crystal: Sujit Datta.

Videos

Below are links to videos that illustrate key aspects of the microfluidic devices used in the lab:

Encapsulation in single emulsion drops. For details see Agresti et al. 2010.
- Example #1

Sorting: black and white droplets are sorted into separate channels. For details see Agresti et al. 2010.
- Example #1: sorting mechanism turned off.
- Example #2: sorting mechanism turned on.

Picoinjections. For details see Abate et al. 2010.
- Example #1
- Example #2

Making double emulsions with glass capillaries #1. For details see Utada et al. 2005.
- Example #1
- Example #2
