Effect of amines addition on properties and stability of pegylated Au nanoparticles
Original language description
In this paper, we propose preparation of PEGylated AuNPs by direct sputtering of Au into pure PEG with subsequent addition of amine terminated PEG. Effect of post-deposition amine addition on properties, aging and thermal stability will be discussed. Transmission electron microscopy and dynamic light scattering measurements showed that we have prepared non-agglomerated spherical NPs with size ranging from 2.9 to 5.9 nm depending on parameters of the preparation. Aging and thermal stability results revealed significant changes in the spectra after addition of PEG–NH2. Differences in the optical absorption spectra can be assigned to change of refractive index (concentration of amine groups on NPsʼ surface) on the metal core and solvent interface with time and temperature.
