Polyethyleneimine (PEI)-modified magnetic iron(III) oxide (Fe3O4) nanoparticles are a composite nanomaterial that combines the properties of magnetic nanoparticles and polyethyleneimine. Polyethyleneimine is a highly branched polymer with a high density of amino groups. These amino groups stabilize the Fe3O4 nanoparticles and provide sites for further functionalization. The amino groups of PEI impart a high surface positive charge to the Fe3O4 nanoparticles, which helps enhance their interaction with negatively charged cell membranes.

OA Coated Fe3O4 Nanoparticles (Oleic acid-modified iron(III) oxide nanoparticles) were prepared using a high-temperature pyrolysis method. Oleic acid was added as a surfactant to a solution containing an iron precursor. Oleic acid not only helps control the growth of nanoparticles but also forms a stable coating on the particle surface. The solution containing the iron precursor and oleic acid was heated to a high temperature, typically around 300°C, to promote the thermal decomposition of the iron precursor. At high temperatures, the iron precursor decomposes to produce iron atoms, which aggregate to form magnetic nanoparticles. During pyrolysis, the iron nanoparticles react with oxygen in the air to form iron(III) oxide (Fe3O4).

Thiol-modified magnetite nanoparticles are prepared via high-temperature pyrolysis and surface-modified with thiol functional groups. Magnetite is widely used in magnetic resonance imaging, magnetic separation, targeted drug delivery, tumor hyperthermia, cell labeling and separation, as a contrast agent, and in retinal detachment repair surgery due to its stable properties, good biocompatibility, high strength, and lack of toxicity. It is also used as a catalyst carrier, microwave absorbing material, and magnetic recording material. Xianfeng has developed numerous derivatives of magnetite, including oleic acid-modified magnetite, magnetite with different PEG ends, DMSA-modified magnetite, polylysine-modified magnetite, carboxylated dextran-modified magnetite nanoparticles, streptavidin-modified magnetite particles, thiol-modified magnetite magnetic nanoparticles, and polyethyleneimine (PEI)-modified magnetic magnetite nanoparticles, among others.

APTS Fe2O3 Nanoparticles (Aminated ferric oxide magnetic nanoparticles) are magnetic nanomaterials modified with amino functional groups using APTS. This material consists of a ferric oxide (Fe3O4) nanoparticle core and an amino (-NH2) surface modification layer.
