Introduction: UV lamps are important equipment used to disinfect and disinfect hospital and research environments, as well as water disinfection of bacteria, and to investigate the mechanisms by which UV wavelengths cause bacteria to disintegrate, It is important to us.
Methods: Searching for keywords with the title/abstract filter in the PubMed database resulted in a total of 71 articles, of which 14 were studied over the last 5 years, of which 10 were used for this review study.
Results: According to research on Pseudomonas aeruginosa, Legionella pneumophila and surrogate microorganisms, the most effective efficacy of UV diodes for water disinfection at 265 nm was determined.Investigations on Cryptosporidium parvum bacteria as well as Bacillus pumilus spores using an adjustable laser from the National Institute of Standards and Technology to isolate UV wavelengths only at 10 nm between 210 and 290 nm, above 240 nm, all The bacteria and viruses tested showed a relative peak sensitivity of between 260 and 270 nm.
Conclusion: Since urinary catheters are the most common infections of the hospital's urinary tract, the main cause of which is Escherichia coli. By examining it at 385 nm and 420 nm after 2 and 6 hours, it can produce a positive inactivation. As a promising antimicrobial technology to prevent biofilm formation in urethral catheters.
