Z18 Engineering has developed a novel technology that utilizes recyclable magnetic nanoparticles (RMNPs) for PFAS removal in water systems. These RMNPs feature a core–shell structure, consisting of an iron oxide magnetic nanoparticle core, surrounded by a functional ligand shell. During the incubation process, PFAS molecules in aqueous solution spontaneously bind to the ligands on the RMNP surface, without the need for external energy inputs such as electricity, light, or heat. Once PFAS binding is complete, the RMNPs can be efficiently separated from the treated water using a magnetic field, either through an applied current or a permanent magnet.

Bing Cao is the President and majority owner of Z18 Engineering. Her academic journey led her to attain a master's degree in Biosystem Engineering from the University of Tennessee. Since 2023, she has been conducting PFAS assessment projects for Superfund (CERCLA) sites and has actively participated in reviewing and editing PFAS monitoring documents in the state of Tennessee. She has served as the principal investigator of the Recyclable Magnetic NanoParticles innovation research team since 2022.
