Aerosol Direct Writing and Thermal Tuning of Copper Nanoparticle Patterns as Surface-Enhanced Raman Scattering Sensors

Surface-enhanced Raman scattering (SERS) substrates are of great interest for detecting low-concentrated analytes. However, issues such as multistep processing, cost, and possible presence of hazardous substances in the fabrication still represent a significant drawback. In this paper, an innovative direct writing method is introduced for...
