A chemist at Washington University in St. Louis is making molecules the new-fashioned way — selectively harnessing thousands of minuscule electrodes on a tiny computer chip that do chemical reactions and yield molecules that bind to receptor sites. Kevin Moeller, Ph.D., Washington University professor of chemistry in Arts & Sciences, is doing this so that the electrodes on the chip can be used to monitor the biological behavior of up to 12,000 molecules at the same time.
