Some Photos

Here are some pictures of hydrogels. I took these pictures to show the difference between those that were rotated during polymerization and those that were not. In the pictures the grain you see is the fibrin, thats the material we were trying to get to NOT settle by rotating.

The hydrogels:

Gradient from no rotation

No Gradient! Notice that there is little fibrin on the outside edges!

Another gel with gradient from no rotation.

A well mixed sample from rotation. This one looks very promising. That blue you see towards the top is probably from the ink on the glass that I am imaging through
