Figure 2. QCM-D analyses of the unmodified and the 1% TiBP functionalized silk protein binding to a titanium coated quartz crystal.

Figure 2

Binding of unmodified silk and binding of 1% TiBP-silk protein on TiO2 coated quartz crystals, detected by dissipation (ΔDn, panel A) and frequency (Δfn, panel B) shifts at three overtones, n= 3 (15 MHz), n=5 (25 MHz) and n=7 (35 MHz). Arrow 1: Protein injection; Arrow 2: buffer rinsing.
