Lead author Eleni Stavrinidou, a postdoctoral researcher in Berggren's lab, cut the stems of roses and then placed the roses in a solution with a variant of the organic polymer poly(3,4-ethylenedioxythiophene) called PEDOT-S:H, which has good electrical conductivity when hydrated.
After the cut flowers had soaked in the solution of PEDOT-S:H for a day or two, the team peeled back the outer layers of the rose bark, revealing tiny "wires" of the organic polymer that had snaked up 2 inches (5 centimeters) into the stem, the researchers reported today (Nov. 20) in the journal Science Advances.
