Abstract

Stomatocyte-like hollow polydopamine nanoparticles (SHPNs) are synthesized for rapid removal of water-soluble dyes from water. They demonstrate an exceptionally high adsorption capacity of 2896 mg g^-1 for methylene blue (MB) and can rapidly sequester MB from water within 20 seconds. Moreover, SHPNs can be regenerated easily using a mild washing procedure.
