SERS up : Ag nanosheet‐assembled structures with controlled morphologies were achieved on indium tin oxide substrates by galvanic‐cell‐induced growth (see figure). These structures exhibit a highly active and homogeneous surface‐enhanced Raman scattering (SERS) effect, and show promising potential as reliable SERS substrates for detection of trace polychlorinated biphenyls.
