Chemists have used visible light and extremely tiny nanoparticles to quickly and simply make molecules that are of the same class as many lead compounds for drug development. Driven by light, the nanoparticle catalysts perform chemical reactions with very specific chemical products — molecules that don’t just have the right chemical formulas but also have specific arrangements of their atoms in space. And the catalyst can be reused for additional chemical reactions.
