Multi-compartment Droplets (IMAGE) Penn State Caption A new method by researchers at Penn State allows the creation of compartments within a liquid that do not have physical barriers, which could improve understanding of compartmentalization in biological systems. In this false colored fluorescence microscopy image, multi-compartment polymer-rich droplets were created in a water-based environment. Three of the six polymers used to create the droplets in this system are fluorescently labeled, therefore the color of each compartment describes its composition.
