Fig. 6From: Green Synthesis of Metal and Metal Oxide Nanoparticles and Their Effect on the Unicellular Alga Chlamydomonas reinhardtiiEffect of a Au, b Pt, c Pd, d Ag and e CuO nanoparticles (1, 5, 10 and 20 mg/L) on photosystem II efficiency (QY %) after 1, 3, 5 and 24 h. One hundred percent on the y-axis represents the QY of the control algal culture without nanoparticles. The error bars represent the standard deviation of repeated experiments of duplicated samplesBack to article page
