Researchers at the University of Toronto have used a combination of synthesized DNA and semiconductors to create a nano-scale antenna that harnesses light. Ted Sargent, says that the tiny antenna consists of tiny semiconductors arranged in a cross-like shape, held together by DNA .

"DNA is something you can synthesize in a lab, and you can program exactly the sequence that you want it to have." Sargent said. "And the DNA was designed to have two regions. One that was prone to stick to the semiconductors, and the other region which was able to stick to other DNA. Because it contains DNA, this antenna can, with a little startup help, self-assemble."
