mPEG-Phosphate, MW 5k

mPEG-Phosphate,MW5k/Diphosphate-mPEG5000/Pyrophosphate-mPEG5000/mPEG-Pyrophosphate, MW 5k/Pyrophosphate-mPEG5K/mPEG-phosphoric acid, MW 5k/Diphosphate-mPEG5000 is useful to PEGylate metal oxide particles and surfaces to form stable monolayer protection. The strong binding properties of organophosphorus to metal oxides result from the creation of a stable M-O-P structure via phosphate metal coordinative interactions. PEG Phosphate-based coupling agents form self-assembled monolayer on the surface of metal oxide nanoparticles such as iron oxide, superparamagnetic particles and upconverting and down-conversion nanoparticles to form thermodynamically stable nanoparticle dispersion.
