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).

Nanomaterials with sizes ranging from 1 to 100 nm are generally referred to as nanocrystals. The preparation of platinum nanocrystals with controllable morphology was first reported in 1996. Pt, Ag, Au, Rh, and other nanocrystals have been synthesized using various methods. Platinum has a face-centered cubic (fcc) structure, but unlike Ag, Au, and Pd, it rarely forms twins; most platinum nanocrystals are single-crystal structures. XFJ116 platinum nanoparticles were prepared via a chemical reduction method, exhibiting uniform size and good dispersibility, and can also provide platinum nanoparticles with amino and carboxyl terminator modifications.

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.

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).

Selenium (Se) is an essential trace element for the human body, playing a vital role in various physiological activities. In the body, selenium is bound to selenocysteine, an amino acid used to synthesize several selenoproteins. Selenium is often the active site of these proteins, playing a crucial role in maintaining intracellular redox balance. Chitosan-stabilized selenium nanoparticles (CS-SeNPs) are nanomaterials using the biopolymer chitosan (CS) as a stabilizer. Through electrostatic interactions, chitosan coats the surface of selenium nanoparticles (Se NPs), improving their dispersibility, stability, and biocompatibility. Se NPs themselves are characterized by low toxicity and high bioactivity, and the introduction of chitosan further enhances their functionality and application potential, making them widely recognized in biomedicine, food, and agriculture.
