A photochemical method has been exploited for the very fast synthesis of electrically conductive Pd nanowires on DNA. The nanowires have an average diameter of 55-75 nm and a length of similar to 3-5 mu m. Our result signifies that the DNA acts both as a reducing agent as well as nonspecific capping agent for the Pd nanowire synthesis. The current voltage (I-V) characterization indicates that the nanowires are continuous and exhibit Ohmic behavior with low contact resistance. The deposition is highly selective on DNA only. Our experiment indicates that I'd nanowires may be valuable as interconnections in nanoscale integrated circuitry, functional nanodevices and in optoelectronics.
