Active gap control on surface‐enhanced Raman scattering (SERS) measurements is performed using tunable plasmonic nanostructures, which are fabricated through the formation of gold nanoparticle self‐assembled thin films on solid substrates and their subsequent transference onto polyacrylic acid gel. When hemoproteins are used as targets, signal intensities increased more than 10‐fold due to this active gap control.
