MagNanoTrap enrichment empowers ultra-sensitive quantification of mixed nanoplastic particles from environmental water samples.

ABSTRACT: Detection and quantification of nanoplastic particles (NPs) in environmental water are important for monitoring NPs' fate and assessing health impacts, but the lack of sensitive and universal detection systems hinders regulation according to the EU Commission (Allan, J. et al., 2021). The MagNanoTrap termed enrichment platform is based on a bifunctional peptide (LCI-DZ-MBP1) combined with Fe₃O₄ superparamagnetic nanoparticles (SPIONs); the bifunctional peptide was designed to decorate SPIONs for NPs capture, with the LCI-peptide binding to SPIONs and the MBP1-peptide acting as a general binder for polypropylene (PP), polyethylene (PE), polystyrene (PS), and polyethylene terephthalate (PET) particles. The MagNanoTrap enrichment platform, with a maximum MagNanoTrap adso
