LOOK AGAIN ...
Just for Fun!
See if you can find the 8 differences in each set of images.
SEM cross section
ECM, the natural nanomaterial
Scanning electron microscope cross section of a columnar Cu2ZnSnS4 film on Mo. The sample was annealed using an unconventional technique, which resulted in local phase separation and partial film delamination.
The extracellular matrix is the microenvironmental material of a tissue that is produced by local cells. Typically it is composed of protein polymers enriched with sugary branches (shown here are fibronectin fibers). It is also known for sequestering or storing and then liberating or activating molecules such as growth factors and matrix proteases, thus directly affecting cellular behavior. The confocal acquired image indicates a six-day chronological matrix deposition represented by different colors (each raw material color was supplemented every other day).
