Fig. 2From: A dual electro-optical biosensor based on Chlamydomonas reinhardtii immobilised on paper-based nanomodified screen-printed electrodes for herbicide monitoringGrowth curve of C. reinhardtii 28 strains reported in Table 1, measuring the optical density (O.D.) of the cell suspension at 750 nm wavelength. Cells are growth in TAP at 25 °C under continuous light 50 µmol photons m−2 s−1 and continuous stirring at 150 rpm (n = 3)Back to article page
