Absolute Mag™ PEG-COOH Iron Oxide Nanoparticles, 10 nm(WNM-X031)


Absolute Mag™ PEG-COOH Iron Oxide Nanoparticles, which are coated with amphiphilic polymer and PEG-COOH, are water soluble iron oxide nanocrystals. With the carboxylic reactive group, their zeta potential is from -15 mV to -5 mV. Their organic layers contain a monolayer of oleic acid and a monolayer of amphiphilic polymer and a monolayer of PEG-COOH, whose thickness is about 6 nm.
Absolute Mag™ PEG-COOH Iron Oxide Nanoparticles can be conjugated to amine containing molecules with low non-specific binding and very stable in most buffer solutions in the pH range of 4-10.
