“Combinatorial Mixer” shows a section of a tiny mixing device. It takes two fluids, dilutes them into four, then mixes them in every possible combination. The result is this mesh of color

A Flikr group called “Art on a Chip” shows an artistic side to a hot area of technology: microfluidics devices. In the group a vibrant collection of images shows cells, channels and fluids on the micro scale. Researchers are encouraged to upload a favorite picture captured through their research, says the curator of the online collection, Albert Folch, an associate professor in BioMEMs and Microfluidics at the University of Washington.
“Our fields of research are bursting with art,” Folch says in his introduction to the website. “I am willing to bet that your hard drive contains at least one gorgeous image that will make me catch my breath.”
