AFM images of pristine PET, PET treated by plasma (PET/plasma), plasma treated and etched. In (i) methanol (PET/plasma/MeOH), (ii) solution of ethanedithiol (PET/plasma/ED) and (iii) biphenyldithiol (PET/plasma/BFD), plasma treated + grafted with BFD + Au nanoparticles (PET/plasma/BFD/Au). Ra is average surface roughness in nm.
