Characterization of Silk Fibroin Modified Surface: A Proteomic View of Cellular Response Proteins Induced by Biomaterials

Table 2

Frequency shifts of QCM and weights of adhered fibroblasts on the electrodes decorated with nonmodified surface, CNTs, and CNTs/SF layers for 12 h of cell incubation.

Cell adhesion	Δ𝐹 (×10^3 Hz)	Δ𝑚 (×10^3 ng)
Nonmodified surface	−16.05±0.44	11.02±0.30
CNTs	−24.85±0.30^∗	17.07±0.21^∗
CNTs/SF	−29.43±0.77^∗	21.52±0.49^∗
