Optimization of pore diameter, the placement of nanoparticles, and the transmission of surface‐enhanced Raman scattering (SERS) substrates are found to be very critical for achieving high SERS activity in porous alumina‐membrane‐based substrates. SERS substrates with a pore diameter of 355 nm incorporating silver nanoparticles show very high SERS activity with enhancement factors of 10 10 .
