This video was made using millions of nanoparticles and microparticles in two tree-like microfluidic devices. A behind-the-scenes video will be made available shortly.
The 200nm yellow green nanoparticles and 2um Red microparticles used were purchased from ThermoFisher (see http://www.thermofisher.com/ for more information).
The microfluidic master moulds were fabricated using a FormLabs Form 2 3D Printer. When cast upon with PDMS, a replica of the microstructures are produced on the PDMS block. The PDMS block is punctured to create an inlet and bonded to a glass slide. The microfluidic channels were filled with particles for this holiday video (see https://goo.gl/bzbROO for more information).

The video was created, filmed and edited by Matthew Hockley, a PhD student from Sabine Hauert’s group.
