By Jon Evans QUANTUM dots – tiny pieces of semiconductor – have already proven their worth in medical imaging thanks to their bright rainbow colours. Now it turns out they’re also extremely good at making deliveries inside living cells. This is great news for the technology of RNA interference (RNAi), which involves blocking the action of messenger RNA, the molecule that carries the chemical “blueprint” of proteins from the genes in a cell’s nucleus to the ribosomes where the proteins are made. If the messenger RNA is intercepted,
