WebJan 1, 2024 · Considering the blocking of UV rays by the porous structure of the 3D-printed porous Ti6Al4V implants, UV led beads were installed in such a way as to create a device containing a (3 × 3 × 4 cm) irradiation cube, in which the values of radiation intensity were more than 2 MW/cm 2 (270 nm) and 30 MW/cm 2 (365 nm). These two intensities and … WebTitanium disks were acid etched to create micropits on the surface. Micro-nano-hybrid surfaces were created by depositioning 300-nm diameter TiO 2 nodules onto the micropits using a previously established self-assembly protocol. These disks were stored for 8 weeks in the dark to allow sufficient aging, then treated with UV light for 48 hours.
