Abstract

The kinetics of assembly of polyethylene glycol (PEG)-coated superparamagnetic Fe3O4 nanoparticles in aqueous suspension on planar Si(Ti)O2 surfaces have been determined using high-resolution optical waveguide lightmode spectroscopy (OWLS). Analysis of the results revealed that the initially uniform population was spontaneously transformed into two types of particles with significantly different adsorption behaviour.
