Abstract
A metal substrate obtained by agglomerating 5 nm to 100 nm metal nano-particles (including clusters) having SERS activity on a metal substrate having a lower electrode potential (higher ionization tendency) than the electrode potential of the metal nano-particles, and fixing the metal nano-particles in an optimally agglomerated state that acts as hot sites, when a detection specimen is adsorbed in a non-dried state, and a predetermined laser light is irradiated, the surface enhanced Raman scattered (SERS) light of antigen detection specimen can be detected by surface Raman resonance in an optimally agglomerated state.
