Fig. 2From: Green Synthesis of Metal and Metal Oxide Nanoparticles and Their Effect on the Unicellular Alga Chlamydomonas reinhardtiiGrowth rate of Chlamydomonas reinhardtii exposed to Au, Pt, Pd, Ag and CuO metal and metal oxide nanoparticles (1, 5, 10 and 20 mg/L). The growth rate for the non-exposed control (algal culture) was 1 × 106 cells/h after 24 h. The error bars represent the standard deviation of repeated experiments using duplicate samplesBack to article page
