We have discovered that nanoparticles analogous to Prussian blue (also known as Hokusai blue or Hiroshige blue) exhibit excellent surface-enhanced Raman spectroscopy (SERS) performance by doping with various metals. The crystal defects created by the addition of the metal contribute to the SERS manifestation, and the addition of different metals can control the SERS performance. The SERS substrate of Prussian blue analogue nanoparticles showed high sensitivity, homogeneity, durability, fluorescence quenching, preservability, and biocompatibility. These results indicate the possibility of developing a new field of "anywhere, anyone, simple, in-situ, low-cost chemical analysis".
