The Effect of Irradiation with a 405 nm Blue-Violet Laser on the Bacterial Adhesion on the Osteosynthetic Biomaterials

Figure 5

Photographs of tryptic soy agar plates in the stamp assay. The effects of irradiation with a 405 nm blue-violet laser on bacteria adhered to the surface of Ti (a, c, e) and HA-PLLA (b, d, f) were analyzed by counting the numbers of colonies formed on tryptic soy agar plates. Compared with the nonirradiated control plates (a, b), colony formation was inhibited by the irradiation for 180 s (c, d) and 300 s (e, f) in both materials.
