SUMMARY:Harnessing Magnetic Nanoparticles
DESCRIPTION:Miroslava Nedyalkova and Marco Lattuada (University of Fribour
 g)\n\nPer- and poly-fluoroalkyl substances (PFAS) have emerged as persiste
 nt environmental pollutants, posing significant risks to human health and 
 ecosystems due to their extreme chemical stability (also known as forever 
 chemicals) and bioaccumulation potential. Conventional remediation approac
 hes, such as adsorption and degradation, have shown limited efficacy in fu
 lly eliminating PFAS from contaminated water sources. In this perspective 
 talk, we want to explore and explain how applying nanoparticle-based strat
 egies could be a transformative solution for PFAS mitigation. \nWe will di
 scuss the application of iron oxide magnetic clusters for PFAS remediation
  and address the remaining gaps in the literature. \nA comprehensive under
 standing of PFAS-specific adsorption mechanisms, particularly at the molec
 ular level, where computational approaches could provide deeper insights, 
 is needed. Most functionalization strategies focus on simple surface modif
 ications, while dual-functionalized or stimuli-responsive coatings remain 
 underexplored. \nPFAS molecules exhibit amphiphilic properties. Current fu
 nctionalization strategies often rely solely on electrostatic interactions
 , which may be effective for long-chain PFAS but fail to efficiently captu
 re short-chain PFAS, which are more hydrophilic and challenging to remove.
 \nStrategies such as coatings incorporating pH-responsive polymers can fac
 ilitate pH-controlled PFAS desorption. Also, light-sensitive materials, su
 ch as azobenzene-functionalized surfaces, could enable PFAS capture.\n\nDo
