Possibly the geekiest art form, DNA Origami involves making shapes out of DNA in two and three dimensions. This can however only be done at the nanoscale. Since then, it has gone beyond being a niche hobby art form and has found a number of applications — from drug delivery systems to uses as circuitry in plasmonic devices. While it usually has to be built like Lego blocks, researchers now claim to have developed a new algorithm that allows the programmed design of a wide range of DNA structures. The development holds important implications for numerous fields, including nanoparticle synthesis and delivery, photonics and memory storage, among others. However, most applications remain in a concept or testing phase.
