On-chip quasi-in vivo cardiac toxicity measurement assay fabrication. (a) Relationship of field potential profile (FP) of single cardiomyocyte (A), quasi -in vivo ECG signals convoluted from FP profiles of lined-up cardiomyocyte network (B), and the surface electrocardiogram (ECG) of individuals (C). (b) System set-up. (c) Fabrication procedure of closed circuit-shaped lined-up cardiomyocyte network. (d) Crossectional view of loop electrode chip. (e) Phase-contrast image of the ring-shaped closed circuit electrodes. Bar, 1 mm.
