Thiol-modified gold nanoparticles deposited on silica support using dip coating

- Thin layers of gold were deposited on glass substrate.
- Layers were modified by two different ligands, 1,4-dithiothreitol and l-glutathione.
- Red shift of SPR band was observed in spectra after modification of Au by thiols.
- Charge transfer between Au and S atoms leads to ferromagnetic behaviour of samples.
