Researchers use bacteria growing on the plate as a tool for evolving molecules such as antibodies. The instrument in the background allows binding characteristics to be determined quantitatively. Shown are Thomas Barker, an associate professor in the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University, and Ashley Brown, a post-doctoral fellow in Barker’s laboratory.
