An aerosol-based soft lithography to fabricate nanoscale silver dots and rings for spectroscopic applications

Site-selective deposition of aerosol Pd nanoparticles on a substrate was employed to fabricate nanoscale Ag dots and rings through a subsequent electroless deposition. The fabricated nanoscale dot and ring arrays respectively showed properties in surface-enhanced Raman (SER, with a 1.8 x 10(5) enhancement factor) and Fourier transform near infrared (FT-NIR, at 6153 cm(-1) absorption band) spectra.
