metals nanoparticles and ecotoxicity

Metal nanoparticles, at least silver and gold, you can easily order from SigmaAldrich, see

http://www.sigmaaldrich.com/catalog/search?term=Silver%2C+dispersion&interface=Product%20Name&N=0+&mode=mode%20matchpartialmax&lang=en®ion=SE&focus=productN=0%20220003048%20219853286%20219853235

You can then dilute the dispersions with a miscible solvent to the concentration you need adding 9 volumes to 1 to decrease concentration 10 times etc.
