Princeton University researchers have developed a technique for testing chemicals with an eye toward "accelerated serendipity" in making key discoveries. The method involves the use of robotics to complete more than 1,000 chemical reactions a day with novel molecular combinations, shedding light on speedy ways to form drug-like compounds. "Instead of having to construct these important molecules circuitously using lots of different chemistry over a period of days if not weeks, we can now do it immediately in the space of one chemical reaction in one day," said David MacMillan, the James S. McDonnell distinguished university professor of chemistry at Princeton. Article
