Synthesis and Characterization of Gold Nanowires in Organic Media
Research Mentor(s)
Bao, Ying (Materials scientist)
Description
Gold based nanostructures such as nanowires demonstrate its unique optical, electrical and mechanical properties. Thus, gold nanowires (AuNWs) have widely been used as building blocks for sensing devices, chemically and biochemically. AuNWs are successfully synthesized in organic media and characterized via Scanning Transmission Electron Microscopy (STEM) and Atomic Force Microscopy (AFM). The parameters were first adjusted and fixed to optimize NWs and minimize spheres in the sample and eventually modified the parameters to acquire different lengths of AuNWs. The biggest challenge and an on-going problem is the contamination of the product from the solvent that caused the imaging to form dark shaded plates, which made the imaging process difficult. Thus, the results from the imaging became less reliable due to the inability to focus on the image when high magnification is applied.
