Miniaturization has become the key word for development in any research field, and "nanotechnology" is a promising technology for miniaturizing and interconnecting different areas of study whether engineering, physics, chemistry or biology. Nanostructures are filling in the empty spaces, and forming a bridge in between different areas for useful applications in biological sensors, optoelectronic devices, biomedical healthcare devices, magnetic sensors and so on. In this work, we focus on the laboratory synthesis of one such nanostructure "Nanowires", which is produced by the bottom-up synthesis approach by the use of electrochemical deposition on aluminum substrates. The research focuses on the use of a template based technique by the formation of porous surfaces in the aluminum substrate known as anodic alumina membrane in order to facilitate the electrodeposition of noble metal nanowires. The anodization of the aluminum template by the use of different acids like oxalic acid, sulfuric acid and phosphoric acid yield different sizes of pores which provide a template for the growth of nanowires. In this research, we have used these three acids to get variety in the sizes of pores ranging from 30 nm to 200 nm. Multi-step anodization techniques yield ordered arrangement of pores providing an ordered template for electrochemical deposition of metal nanowires. Primarily noble metals like gold (Au), silver (Ag), and platinum(Pt) were used for the electrodeposition process. The morphology and structure were characterized by using microscopy techniques such as Atomic Force Microscopy (AFM), Scanning Electron Microscopy (SEM), and elemental analysis using Energy Dispersive Spectroscopy (EDS).
