DNA-based nanobarcodes

The idea is one of several applications the researchers have found for what they call "dendimer-like DNA," consisting of many short Y-shaped strands of DNA linked together in a treelike structure. The DNA that carries the genetic code in living cells consists of two complementary strands that attach to one another along their length. But Luo's research purposely and completely ignores the DNA's genetic coding properties. He uses DNA, he said, as a "generic instead of a genetic material."
