Cat. No.: HY-184630
Polylysine-modified magnetite nanoparticles are a composite material. Modifying Fe3O4 nanoparticles with PLL can form Fe3O4@PLL composite material, which combines the magnetic properties of Fe3O4 with the biocompatibility and multifunctionality of PLL.
Cat. No.: HY-184625
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.
Cat. No.: HY-184632
Fe3O4 nanorods are a type of nanomaterial with a unique morphology, consisting of a rod-shaped structure with a specific ratio between length and diameter.

Synonyms: 4-Acetamidobenzaldehyde
Cat. No.: HY-184635
Monodisperse Fe3O4 microspheres (Monodisperse iron oxide microspheres) are microspheres composed of magnetic materials, with iron oxide as the main component. These microspheres are very uniform in size and exhibit monodispersity, meaning that the sizes of the microspheres are very similar with minimal differences.
Cat. No.: HY-184634
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).
Cat. No.: HY-184629
Ultra-small magnetic iron oxide nanoparticles refer to iron oxide (Fe3O4) nanoparticles with very small size. These nanoparticles typically have a diameter of less than 10 nanometers (<10 nm), and the size observed by TEM is usually in the range of 5-10 nm.
Cat. No.: HY-184631
Carboxymethyl dextran-modified iron(III) oxide nanoparticles are composite materials in which carboxymethyl dextran (CMD) is introduced onto the surface of iron(III) oxide (Fe3O4) nanoparticles through chemical modification. Carboxymethyl dextran is a water-soluble polysaccharide; its hydrophilicity and biocompatibility are enhanced by converting the hydroxyl groups of the dextran into carboxymethyl groups (-COOH).
Cat. No.: HY-184627
The core material of carboxylated dextran-modified iron oxide nanoparticles is iron oxide (Fe3O4), which possesses superparamagnetic properties, making it suitable for applications requiring magnetic field response. The surface is coated with carboxylated dextran, a modification that increases the nanoparticles' water solubility and biocompatibility, while also providing carboxyl functional groups, facilitating further chemical modification and biomolecular coupling.
Cat. No.: HY-184633
Hollow mesoporous iron oxide nanoparticles are a type of nanomaterial with a special structure that combines hollow structure with mesoporous (mesoporous refers to pores with a diameter between 2 and 50 nanometers) characteristics. They are mainly composed of iron oxide (Fe3O4) with a hollow center. This structure can increase the specific surface area of the material while reducing its weight, thereby improving its application efficiency in fields such as catalysis and drug delivery.
Cat. No.: HY-184620
Ferric oxide (Fe3O4) is widely used in magnetic resonance imaging (MRI), magnetic separation, targeted drug delivery, tumor hyperthermia, cell labeling and separation, and as a contrast agent and enhancement agent in retinal detachment repair surgery due to its stable material properties, good biocompatibility, high strength, and lack of toxic side effects. It is also used as a catalyst carrier, microwave absorbing material, and magnetic recording material. Xianfeng has developed numerous derivatives of ferric oxide, including oleic acid-modified ferric oxide, PEG-terminated ferric oxide, DMSA-modified ferric oxide, polylysine-modified ferric oxide, carboxylated dextran-modified ferric oxide nanoparticles, streptavidin-modified ferric oxide particles, thiol-modified ferric oxide magnetic nanoparticles, and polyethyleneimine (PEI)-modified magnetic ferric oxide nanoparticles, among others. This wide range of modifications provides numerous options for subsequent experiments.
Cat. No.: HY-184626
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.
