Technique monitors thousands of molecules simultaneously

ific electrodes. "What electrochemistry does best is to reverse the polarity of things," Moeller said. "It takes things that are electron-poor and makes them electron-rich and vice versa; it can take an oxidant and turn it into a reductant; a reductant into an oxidant; a base into an acid and an acid into a base; and so on. In the end, almost any chemical reagent can be made at an electrode and used on the chips."

Moeller said that , along with emphasizing new reactions, he and his collaborators are working to better identify the molecules they make on the chips, and perfect the signaling techniques used to monitor molecules on the chips. He praised the time-of-flight secondary-ion-mass spectrometry work of his Washington University colleague Amy Walker, Ph.D., assistant professor of chemistry, in the monitoring of his system.
