Click Chemistry came about as several researchers came to similar conclusions in parallel, but from different angles: Barry Sharpless, Morten Meldahl, and Carolyn Bertozzi. We hear about their research goals in the 1990s and early 2000s: to snap together smaller molecules in a reliable way, perhaps with pharmaceutical or biological experiments and results in mind. We learn of Sharpless's goals for Click Chemistry, which sometimes overlap with Green Chemistry.Support the Show.
