Fig. 4: Electrical measurements of sectioned zebrafish brains with A5–ETE-R.
From: In situ assembly of bioresorbable organic bioelectronics in the brain
Zebrafish with electropolymerized A5–ETE-R were left to swim for 1 day or 7 days, brains were excised and sectioned, and then placed on interdigitated Au electrodes for electrical measurements. a–d, a′–d′ Microscopy images depicting brain slices on Au electrodes. Scale bars 500 µm (a–d) and 200 µm (a′–d′). Electrode numbers were overlaid in the images for clarity. a″–d″ Electrical measurements show currents flowing between the indicated electrode leads. n = 3 fish in each group.
