(PhysOrg.com) -- With its unique double-helical structure, DNA has the ability to be used as a programmable building material to construct designer nanoscale architectures. Complex DNA architectures could have a variety of applications, from DNA-based nanomotors to biosensing and drug delivery. Taking the research a step forward, researchers have recently constructed a nanometer-sized tetrahedron from a single strand of DNA, using a method that could have advantages for assembling similar structures on a large scale.
