Emission spectra of PSiMc devices ( λ exc = 490 nm) before and after chemical functionalization and metal device recognition. (a) Thermally oxidized sample, (b) PSiMc/Rh-UTES sensor (derivative (3) concentration = 1.16 μM), and (c and d) PSiMc/Rh-UTES-Hg2+ complexes (3.45 and 6.95 μM respectively).
