Abstract

A convenient approach for hydrothermal synthesis of copper nanowires and their subsequent application in surface-enhanced Raman spectroscopy is presented. The highest enhancement of the Raman spectra of the methylene blue and 1,2-bis(4-pyridyl)ethylene analytes was recorded for thicker nanowires with an average diameter of 72 nm, whereas thinner nanowires, averaging 40 nm in diameter, exhibited reduced enhancement. The observed variation in signal intensity ranged from 5 to 10 times across different concentrations of the analytes. The obtained enhancement factors are 2.5 × 10⁴ and 1.1 × 10⁴ for methylene blue and 1,2-bis(4-pyridyl)ethylene, respectively. These findings underscore the potential of copper nanowires in enhancing the detection capabilities of SERS-based analytical techniques.
