Abstract

A bio-inspired approach for detoxification of water has been investigated. In this approach, three major classes of toxic agents, heavy-metal ions (Cr, Hg, Pb, Cu, and Cd), toxic organic species (4-aminopyridine), and a radioisotope (Lutetium-177) were effectively removed from contaminated water by polydopamine, a mussel-inspired adhesive catecholamine (see figure). In addition, this polydopamine filter was easily regenerated by treatment with acid or hydrogen peroxide.
