Antibacterial and Antibiofilm Activities of the Photothermal Therapy Using Gold Nanorods against Seven Different Bacterial Strains

Figure 1

Characterization of gold nanorods. (a) TEM image of AuNRs: it clearly shows the rod shape of these nanostructures. (b) TEM image of AuNRs after laser exposition showing no changes in the morphology of gold nanorods. (c) Vis-NIR absorption spectrum: transversal and longitudinal plasmon peaks were observed at 540 nm and 810 nm, respectively.
