A Current signal from oxygen evolution of CC125 C. reinhardtii whole cells immobilised on paper-based screen-printed electrodes modified with different (nano)materials. Working stability of C. reinhardtii immobilised on pCB-SPEs evaluated by amperometric (B) and fluorescence (C) analysis. Applied potential − 0.6 V, interval analysis time 0.5 s, repeated cycles of 10 min dark and 30 s light (350 μmol photons m−2 s−1) (n = 3)
