Researchers at the universities of Oxford and Warwick in the UK have used a DNA nanomachine to control a set of chemical reactions in a sort of nanoscale manufacturing line that they have dubbed a molecular assembler. The reactions in question normally occur very slowly, but the DNA molecules help to bring the reactants closer together so they interact faster. The molecular assembler might be used to template a whole range of different chemical reactions to create a library of products, and the DNA tag could help to identify a specific product in this library – for example one that binds to a target protein………
