In this study, magnetic magnetite nanoparticles were synthesized and modified for the covalent immobilization of lipase. Magnetic nanoparticles have attracted considerable attention due to their applications in catalysis, water treatment, biotechnology, biomedicine, and drug delivery. Magnetite nanoparticles with an approximate size of 10–20 nm were prepared using the co-precipitation method...

The use of carbon nanotubes as a solid phase of the extraction of both organic and inorganic compounds provides sufficient absorption capacity. It is also used as a new material in a solid-phase microextraction. Solid phase extraction of some polycyclic aromathic hydrocarbons (PAHs) (naphthalene, anthracene and pyrene) from aqueous solution using carbon nanotubes (CNT) has been investigated....

Organophosphorus pesticides are extensively used in agricultural applications, and their residues in aquatic environments have raised significant environmental and analytical concerns. In this study, a solid-phase extraction method based on functionalized single-walled carbon nanotubes (SWCNTs) was developed for the extraction and preconcentration of diazinon and malathion from aqueous samples...
