Fig. 2. Representative AFM images (topography and phase contrast, recorded in a dry state) of the glass surface silanized with APTES (a) and subsequently functionalized with grafted POEGMA188 brushes (b–e, using different polymerization times TP), compared with the data for the same substrates incorporating AgNPs (f–j) after a 15 min long exposure to 5 mM AgNO3 solution, followed by reduction in 0.2 M NaBH4 solution for 12 h. Cross-line analysis corresponds to the topography of the samples without (green) and with AgNPs (red).
