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.

Synonyms: mPEG750-NH2
mPEG750-amine (mPEG750-NH2) is a chemical modification reagent for nanoparticles, capable of covalently binding to Ad-PVA to form Ad-PVA-PEG polymers. mPEG750-amine stabilizes gene delivery complexes by providing steric hindrance, reducing particle aggregation, while enhancing the water solubility and serum stability of the complex, reducing carrier cytotoxicity, and assisting in the efficient condensation of pDNA by cationic components to form nanoparticles that can be endocytosed by cells. mPEG750-amine can also be used to synthesize folate-conjugated polymer micelles for encapsulating the anticancer agent Camptothecin (HY-16560). Folate-conjugated polymer micelles are effective carriers for poorly soluble anticancer drugs, capable of avoiding macrophages and acting through folate receptor (FR)-mediated endocytosis to target tumor cells. mPEG750-amine can be applied to research in the field of non-viral gene delivery, as a component of gene delivery vectors, facilitating the safe and efficient delivery of nucleic acid drugs to target cells .
