Fabrication of metal-DNA and metal-CNT hybrid nanomaterials

This paper reports fabrication methods for ordered metallic nanostructures such as nanowires and nanoparticles based on deoxyribonucleic acid (DNA) templates. The phosphate groups in DNA are negatively charged; consequently, the DNA conformation may mineralize metals e.g., palladium (Pd) at a relatively high metal concentration. We successfully form unique spherically shaped moss-like hybrid Pd nanoparticles using the small compacted globular state of DNA by controlling the reductive reaction [1,2]. This paper also shows the fabrications of Pd-carbon nanotube (CNT) [3,4] and silver (Ag)-CNT [5] hybrid nanomaterials as shown in Fig.1.
