"This image shows electrically conducting plastic nanofibers that can serve 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. [It is] part of subset of experiments geared towards discovering biological applications for conducting polymer nanofibers."
