APTS@ Fe2O3 Nanoparticles

Product Name

Name:a>APTS@ Fe2O3 Nanoparticles

^{Product Overview}

Aminofunctionalized iron oxide magnetic nanoparticles are magnetic nanomaterials modified with amino functional groups via APTS. This material consists of a core of iron oxide (Fe3O4) nanoparticles and an amino (- NH2) surface modification layer. The aminated surface helps to improve the biocompatibility of the nanoparticles and reduce toxicity to cells. Amino functional groups can be further chemically modified for coupling biological molecules such as drugs, proteins, and nucleic acids. Amino functional groups undergo protonation at different pH values, resulting in nanoparticles having different surface charges in different pH environments.
