文摘

Different bulk structure of initial MF and PEG modified MF was confirmed. PEG modification of MF transforms small MNPs aggregates to large and developed. Individual non-aggregated nanoparticles are preferably adsorbed on oxidized silicon. Nanoparticles from MF form a single adsorption layer on the silicon surface. PEG modified MF compose large developed aggregates that are not adsorbed by surface.
