The Bradley group has developed a platform allowing fabrication of polymer microarrays, consisting of thousands of polymers on a single microscope slide. These slides can be interrogated with a variety of cells, with subsequent high-content screening, allowing the identification of a specific polymer that binds or otherwise modulates cellular function. Importantly, once the specific polymer has been identified they have shown that this can be seamlessly scaled-up to allow much larger scale application. They have used polymer microarrays for the identification of polymers to control stem cell differentiation and global transfection, find polymers for bacterial scavenging and capture and polymer matrices that promote and stabilize hepatocyte function.
