Can commerercially available filtration membranes be easily functionalized in such a way to enhence the removal the charged contaminants in the water treatment process? The literature demonstrates there have been two pioneering works that demonstrated that Ultrathin Self-Assembled Nanoparticle (USANP) membranes (composed of ~5 nm diameter metallic gold nanoparticles surrounded by organic ligands) when applied to commercial membranes displayed charge sensitive rejection to molecular dyes and also have the ability to charge modify the openings in commercial filters. The rejection mechanisms in these works are proposed to be either size dependent or charged based. Recent experimental results have demonstrated that …
