Figure 3.

Change in dissipation as a function of the change in frequency (ΔD_n – Δf_n/n) of the overtone n = 3 corresponding to unmodified t-CNC and biotin-functionalized t-CNC (t-CNC–HC-Biot and t-CNC–PEG-Biot, respectively) at 0.5 g L^–1 adsorbed onto SAV-coated surfaces at pH 7. For the purpose of comparison, the ΔD_n – Δf_n/n plot for the adsorption of unmodified t-CNC at 0.5 g L^–1 onto PAH-coated surfaces has been depicted (green line). The inset shows the low frequency and dissipation values in more detail.
