| Abstract: | Poly(amidoamine) (PAMAM) dendrimers are attracting great interest as a consequence of their unique properties as carriers of active molecules in aqueous media, as we expect their presence in the environment to be widespread in the future.In this article, we focus on the analytical methods to characterize and to determine these polymeric materials in waters and on their ecotoxicity for aquatic organisms. We review physical characterization techniques (e.g., light scattering, electron microscopy, atomic force microscopy) and analytical techniques, mainly based on liquid chromatography, so as to consider their main capabilities, advantages and drawbacks. We assessed the toxicity of certain PAMAM dendrimers for the green alga Pseudokirchneriella subcapitata by determining the EC50 and correlating it with the ζ-potential. |
