Abstract

The economic and societal impacts of nano-materials are enormous. However, releasing such materials in the environment could be detrimental to human health and the ecological biosphere. Here we demonstrate that gold and quantum dots nanoparticles bio-accumulate into mucus materials coming from natural species such as jellyfish. One strategy that emerges from this finding would be to take advantage of these trapping properties to remove nanoparticles from contaminated water.

Schematic representation of the removal of NPs from an aqueous suspension using mucus secreted by jellyfish (Pelagia noctiluca).

As reported in this contribution, mucus materials can capture quantitatively the NPs present in water (a). The NPs trapped by the mucus layer at the bottom of the sample releasing a decontaminated supernatant (b).
