AFM characterization of the LOF probes. 5 µm × 5 µm top view around the core region of the probes integrated with MGs at concentration of 0.05% (a), 0.5% (d) and 5% (g). AFM images 2 µm × 2 µm top view around the unpatterned region of the probes integrated with MGs at concentration of 0.05% (b), 0.5% (e) and 5% (h), (c), (f), (i) slice processing of figures (b),(e) and (h) highlighting portions with thickness larger (black) and smaller(light blue) than 25 nm.
