• Resumen

  • This paper describes an experiment developed to provide students enrolled in introductory nanotechnology and introductory chemistry courses with an opportunity to synthesize silver nanowires using a bottom-up nanofabrication technique. The reaction between copper metal sputter coated on silicon dioxide and a dilute silver nitrate solution is used to create the nanowires. Included in this experiment is a characterization component allowing students to analyze the nanowires using atomic force microscopy (AFM) and scanning electron microscopy (SEM). Microscale silver wires are also produced in the reaction, making it possible for students to utilize optical microscopy, in addition to AFM and SEM, for silver wire characterization. The silver nanowire synthesis reported in this paper does not require the use of nanoporous templates or hazardous puri?cation steps to liberate wires from template con?nement
