Fig. 6From: Biointerfaces with ultrathin patterns for directional control of cell migrationImpedance monitoring of cell migration using interdigital electrode integrated with patterned TiOx. (a) Normalized impedance versus time for real-time impedance monitoring of MC3T3-E1 cell migration over 90Â h. (b) Correlation between normalized impedance and number of cells after seeding for 10Â h. Cells were initially seeded on edge of sensor regionBack to article page
