Figure 4From: Silica nanoparticles for the layer-by-layer assembly of fully electro-active cytochrome c multilayersFT-IR. FT-IR spectra of synthesized and modified silica nanoparticles. (a) SiO2, (b) SiO2-NH2, (c) SiO2-CO2H. ATR (Diamond) is used with a resolution 8 cm-1, scans 16, in the range of 400-4,000 cm-1.Back to article page
