摘要

The growing use of nanomaterials and their associated risks necessitate the emergence of efficient decontamination systems. The main objective of this study is to develop a new prototype based on artificial supramolecular hydrogel capable of removing nanoparticle (NP) waste and nanomaterial by-products from aqueous suspensions. We demonstrate the high trapping efficacy of the low-molecular-weight gelators (LMWG) for very small particles (quantum dots (QDs), gold nanoparticles (AuNPs), TiO2 nanoparticles (TiO2-NPs), below 50 nm in diameter) from aqueous suspensions. The performance levels of removing nanoparticles from contaminated effluents could lead to a competitive alternative to filtration and dialysis devices.
