NANOTECHNOLOGY UPDATE: Automated synthesis expands nanotechnology building block repertoire. “The main limitation right now is that only 200 building blocks are available that carry both the halogen and the boronate groups, so only these can be used anywhere other than the first or last building block in the chain. If several thousand new building blocks become commercially available, it may not be too much of an exaggeration to talk about 3D printing of small molecules. . . . t will no doubt take several years to see just how big, how diverse, and how complex the products of this molecule synthesizer can be. It seems reasonable to expect a huge effect on drug discovery and other practical areas. Will it contribute to the development of APM? For example, could it synthesize small diamondoid parts? Could it produce useful catalysts or other functional components to attach to a large structural DNA framework? Or perhaps components for smaller, stiffer structural frameworks?” Faster, please.
