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.

PEI stabilized gold nanoclusters (PEI-Au NCs) are nanomaterials combining gold nanoclusters and polyethyleneimine. They consist of a few to dozens of gold atoms forming the core of the gold nanoclusters, while polyethyleneimine (PEI), a positively charged hyperbranched polyamine, is selected as the end-capping agent, encapsulating the surface of the gold nanoclusters. PEI-Au NCs have gained widespread application due to their high luminescence properties and stability over a wide pH range. Furthermore, their good biocompatibility and ease of surface modification or functionalization make them attractive for many biomedical applications.

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.
