||P.504 right column 4th paragraph: "HepG2 cells were cultivated on the Ta2O5 gate insulator at subconfluent levels, using a physically adhered adhesive matrix of poly-l-lysine with a thickness of ∼1 nm (as determined using ellipsometry). The system could be used for any types of adhesive cells such as epithelial cells and fibroblasts [ref 22]."
||P.504 right column 4th paragraph: "The cells remained securely adhered under the shear stress produced by the flow. With a surface density of 3 × 10^5 cells/cm^2 for the subconfluent monolayer of eukaryotic cells, the rectangular sensing area (10 μm × 340 μm) was occupied by approximately 10 whole cells (Fig. 1b)."
