Silver Nanowire MoS2 Substrates for Use in Surface-Enhanced Raman Spectroscopy

Description

Raman spectroscopy provides a structural signature spectrum of molecules based on vibrational modes but suffers from very weak signal production. Therefore, it is necessary to enhance the signal using the method of surface-enhanced Raman spectroscopy. This technology provides a composition of molybdenum disulfide and silver nanowires and a method of producing this composition for use in surface-enhanced Raman spectroscopy for high-sensitivity signal detection.

Miguel Jose Yacaman, John Eder Sanchez, and J. Jesus Velazquez Salazar.

Potential applications

Raman spectroscopy has multiple applications across industries including biomedical, forensics, and pathogen detection, among others.

Benefits and advantages

Most SERS substrates are based on the surface plasmon resonance of metal nanoparticles; this substrate includes nanowires to amplify the effect of the electric field by approximately 104 with respect to a sample without nanowires, therefore enhancing signal detection.
