Abstract
This review reports a new method for the fabrication of ordered metallic nanostructures such as nanowire, nanogrids and nanoparticles based on the use of DNA templates. DNA has negative charge on phosphate groups, so that the DNA conformation can be attempted to mineralize metals e. g., palladium (Pd) on its atructure at a relatively high concentration of metals. We were successful in the formation of unique Pd nanoparticles by controlling reductive reaction. We showed the utilization of the Pd nanoparticles for the highly-sensitive hydrogen sensor.
