Revzin's team collaborated with UCLA electrical engineer Prof. Aydogan Ozcan to integrate an antibody microarray with a lensfree holographic imaging device that takes only seconds to count the number of captured cells and amount of secreted cytokine molecules. The test returns results six to twelve times faster than traditional approaches and tests six parameters simultaneously, based on a small blood sample. The Revzin team published the results of their experiments in the May 2010 issue of Analytical Chemistry.
