| Figure 3: Components and appearance of the multicavity chip (left). Morphology and impedance spectra of spheroids cultivated from five different tissues (right): OLN93 (a), Bro (b), Cos-7 (c),CHO (d), chicken retina cells (e) and two inorganic spherical models (zeolite beads, 300 µm diameter (f) and glass beads (g)). Related impedance spectra varying in amplitude and peak position depending on the object’s porosity (h) [21]. |
