Welcome to the Nano World! Its a single cell on the polymeric matrix. You have to feed them, and control the humidity and temperature around them to survive like a pet. As you can see, this cell lying down on the surface and take a nap! This photo captured by a FE-SEM (a giant microscope) and the real size of the cell is about 20 micrometer. You can see the cell 3D using anaglyph 3D Glasses (Blue/Red glasses).
