Live-staining of biohybrid electrodes. Light microscopy of the electrodes (I) depicting the fibrin layer. Live staining allowed the visualisation of single cells entrapped in the fibrin layer (II and III). Cells survived on the surface of the electrode without any migration as shown in the micrographs of the same area of the electrode array 3 (a), 7 (b), and 10 (c) days after coating
