Query: Highly reproducible, large scale inkjet-printed Ag nanoparticles-ink
  SERS substrate   We report the fabrication of a low cost, and highly reproducible large scale
surface-enhanced Raman spectroscopy substrate using an inkjet-printed Ag
nanoparticle ink (AgNI). The AgNI SERS substrates were evaluated for SERS using
BPY as a molecular probe. The printed AgNI dot arrays exhibit an excellent SERS
performance and reproducibility. The batch to batch and spot to spot standard
deviation value of less than 10 percent was obtained. The results reveal the
reproducibility of the AgNI SERS dot arrays and its potential application for
SERS substrates.
