Synthesis of polypyrrole nanowire network with high adenosine triphosphate release efficiency

► Adenosine triphosphate (ATP) is used for the first time as the morphology-directing agent for the synthesis of polypyrrole nanowire network. ► ATP serves as both the morphology-directing agent and the model drug. ► ATP release efficiency of the PPy nanowire networks is much higher than that of the non-nanostructured PPy films.
