Liver On A Chip? Maybe Someday, Say Researchers
A project designed to culture liver tissue, pioneered by the Massachusetts Institute of Technology (MIT), may help to one day soon save lives. Cell-holding scaffolds for the project are made of laser-machined polymers (polycarbonate, polyethylene terephthalate, and polyimide). Extremely small
