Low-Crowding Environment (IMAGE) University at Buffalo Caption Two protein droplets fuse easily when pushed together (shown sequentially in fluorescence microscope images, top to bottom.) The droplets, made from fused in sarcoma proteins, have a fluid consistency as they sit in a solution sparsely populated by other molecules. Scientists used state-of-the-art optical tweezing technology to grab and manipulate these protein micro-droplets.
