Introducing the short-term antibacterial capabilities of photocatalytic Titanister!
We report the antibacterial test results against Escherichia coli (E. coli) using the photocatalytic material "Titanistar®."
In the photocatalytic industry, tests typically last around 3 to 5 hours; therefore, we confirmed the superiority of the antibacterial reaction through a test with a short ultraviolet lamp exposure time of 1 hour.
【Results of the antibacterial test with 1 hour of ultraviolet exposure】
This time, we conducted an antibacterial test with an exposure time of 1 hour. Using a strain of E. coli, we performed the antibacterial test using the film adhesion method at a concentration of 2.5×10^S, with 1 mW/cm² BLB irradiation. The test area consisted of titanium plates treated with Titanistar, while the control area consisted of untreated pure titanium plates.
After 1 hour, we could not detect any bacteria on the Titanistar-treated plates. In contrast, the number of bacteria on the untreated titanium plates showed little change. This indicates that Titanistar has a high photocatalytic ability.
