Transmission electron microscopy images of a Au, b Pt, c Ag, d Pd and e CuO nanoparticles synthesised using gum karaya and their corresponding metal salts. a, b, c, d and e graph inserts show the peak particle size distribution by nanoparticle weight in algal media, as determined by differential centrifugal sedimentation. (F) UV–Vis spectra for the Au, Ag, Pt, Pd and CuO nanoparticles
