Microfluidic manipulation of magnetic nanoparticles is a smart tool for various environmental and biomedical applications, such as water remediation from pollutant molecules (heavy metals, pesticides, …), high-sensitivity immunoassays, cancer treatment by controlled drug delivery, hyperthermia or mechanical destruction of cells, protein...

In this study, the use of magnetic biochar particles recovered from biorefinery by-products (humins) for adsorption of hydrophilic organic pollutants was investigated. The biochar was prepared by thermal treatment of crude humins followed by a grinding step after which a magnetic iron oxide was co-precipitated on the biochar surface. The...

This paper (part II) is devoted to the effect of molecular adsorption on the surface of magnetic iron oxide nanoparticles (IONP) on the enhancement of their (secondary) field-induced agglomeration and magnetic separation. Experimentally, we use Methylene Blue (MB) cationic dye adsorption on citrate-coated maghemite nanoparticles to provoke...
