"This image shows the inside of a microfluidic chamber containing a line of pillars that are trapping first a layer of hard polystyrene spheres, and then the chamber is filled with model hydrogel spheres (teal). I took this image to see whether the hydrogels were able to be trapped in a regular array in this chamber.
Packed chambers such as this are analogous to packed-bed catalyst reactors used in much of chemical processing. Our goal is to encapsulate liver cells within these hydrogel spheres. Liver cells are often called the chemical processing plants of the body: by packing 'catalytic' spheres of hydrogels containing liver cells, we could then perfuse drugs through the chamber and study the effect that the liver cells have on the drugs."
