Distinguishing Single Cells With Nothing But Light, University of Rochester Study

EurekAlert! -- Researchers at the University of Rochester have developed a novel optical technique that permits rapid analysis of single human immune cells using only light.Availability of such a technique means that immunologists and other cellular researchers may soon be able to observe the responses of individual cells to various stimuli, rather than relying on aggregate statistical data from large cell populations. Until now scientists have not had a non-invasive way to see how human cells, like T cells or cancer cells, activate individually and evolve over time.
