"This image shows a human breast cancer cells (red color) spreading over a porous and texturized polymeric surface (blue color). This cell is supported on nanofibers of an electrically conducting plastic serving as a scaffold for probing cellular growth. These nanofibers can puncture a cell and can be used to inject them with a variety of chemicals that are capable of killing them.

I collected this image in order to study the interaction between a porous polymeric nanofibrillar surface and human cancer breast cells. I was trying to study how fast these cells would spread on a highly doped conducting polymer surface such as 3,4-polyethylenedioxythiophene (PEDOT)."
