The biological outcomes of surface treatment of BGs by using the laser. (I) optical profilometer image of untreated BG (a) (sample1); laser-treated at fluence 1.0 J/cm² and sample scanning speed of 35 μm/s (b) (sample2); and 15 μm/s (c) (sample3). (II) SEM micrographs of sample 3 exhibiting no adherence of S. aureus (a); micrographs showing the attachment of S. aureus (b), P. aeruginosa (c), and (d) E. coli on the surface of untreated BGs. (III) The proliferation of INT407 cell line on untreated BGs, the sample3 and (c) Petri dish. Reproduced with permission from Reference [90].
