Fig. 7From: A dual electro-optical biosensor based on Chlamydomonas reinhardtii immobilised on paper-based nanomodified screen-printed electrodes for herbicide monitoringCC125 C. reinhardtii reversibility tests by amperometric (A) and fluorescence (D) analysis. Matrix effect by amperometric (B) and fluorescence (E) analysis. Study of the interferents by amperometric (C) and fluorescence (F) 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)Back to article page
