Murthy Reactive Oxygen Species (IMAGE) Georgia Institute of Technology Caption Coulter Department of Biomedical Engineering postdoctoral fellows Seungjun Lee and Kousik Kundu and associate professor Niren Murthy (left-right) discuss their experimental results, which show that by replacing a hydrogen atom with a deuterium atom during the synthesis of fluorescent probes, they increased the stability and shelf life of the dyes, and also improved their ability to detect smaller concentrations of reactive oxygen species.
