Scientists use 3D printer to create networks of artificial cells Researchers have developed networks of water droplets that can act like biological tissue cells. The researchers created the networks using a three-dimensional printer. The networks can support up to 35,000 droplets and have the potential to be a scaffold for growing synthetic tissues or a […]
