a Rendering of the planar Organic Electrochemical Transistor, consisting in a glass substrate with Cr/Au contacts and Pedot:Pss channels and gate, enclosed in a PDMS perforated cylinder to implement the culture well. b TECH-OECT with six devices inserted and electrically connected. Optical zooms highlight a viral-infected (red) and a healthy cell line (blu) after 48 h from seeding. Circle diameter of 500 μm. c Schematical graph (left) of the expected OECT responses discriminating a viral-infected culture and a healthy one, with the relative cross-section representations (right). Black arrows represent ionic fluxes across cell layers, which intensify upon layer destruction caused by viral proliferation.
