Atomic concentrations of C (1s), O (1s), S (2s) and Au (4f) in pristine PET (theory and present experiment [17]), plasma-treated sample (sample was measured 170 h after the plasma treatment), plasma treated + grafted in solution of (1) 1, 2-ethanedithiol (ED) or (2) biphenyl-4, 4'-dithiol (BFD) and (3) PET plasma treated + then grafted in ED or BFD + in gold nanoparticles respectively.
