🎴 Does Blue Light Kill Bacteria

The combination of both red and blue LED light inside the mouth is a powerful tool in preventing future disease. LIGHT THERAPY KILLS VIRUSES. The evidence shows that violet/blue (400–470 nm) light is antimicrobial against numerous bacteria, and that it accounts for Niels Ryberg Finsen's Nobel-winning treatment of tuberculosis. Using simple blue light at just the right intensity, researchers at the Forsyth Institute in Boston may be advancing dentistry into a new era. "We were able to eliminate the bad guys in 15-60 seconds," claims Dr. Soukos. …a nd only the so-called "bad guys." The researchers found that eliminating or suppressing the bad bugs – increased the The spectral range of UV light is, by definition between 100 and 400 nm (1 nm=10-9m) and is invisible to human eyes. Out of the three types of UV lights viz. UVA, or near UV (315–400 nm), UVB, or middle UV (280–315 nm), UVC, or far UV (180–280 nm) has gained favor due to its ability to help kill various types of viruses. Oral black-pigmented bacteria (BPB) in pure cultures and in dental plaque samples were killed by 4.2 J/cm 2 blue light, whereas P. melaninogenica required 21 J/cm 2. 3) Propionibacterium acnes was also inactivated by blue light without an exogenous photosensitizer. 4,5) Investigations using a high-intensity xenon lamp, 6) have demonstrated the Although it's been proven that ultraviolet-C light can kill the coronavirus in controlled research environments using specific doses, there's no guarantee that a lamp will. Manufacturers use Our proven Bacteria Blue Light kills a wide variety of pathogenic bacteria including MRSA, Staph, Strep, Listeria, Salmonella and more. As an example EMS passengers sometimes harbor blood borne and airborne pathogens that can be spread to equipment, crew members, and surfaces within the vehicle. EMS vehicles must maintain a superior cleaning While a UV phone sanitizer box is closed, a bright UV-C light shines on the phone and reflective surfaces for anywhere from three to 10 minutes. University of Haifa and Oranim College's Yoram However, the same study showed that only P. gingivalis strains were susceptible to this phototoxicity while in biofilm state. The authors' conclusion was that the dental halogen curing light was “effective in reducing periodontal pathogens in planktonic state” 2 and that this method could be used for the treatment of periodontal disease. Ultraviolet (UV) light was first discovered in the mid-20th century, introducing a new way for people to eliminate viruses and bacteria. Although UV technology has risen to prominence in recent years, especially during the current COVID-19 pandemic, the majority of the general public does not fully understand exactly how UV lighting helps kill viruses and bacteria. It has been found that blue light can mediate a broad-spectrum antimicrobial effect, including both Gram-negative (Feuerstein et al., 2005; Guffey and Wilborn, 2006; Hamblin et al., 2005; Lipovsky et al., 2010; Maclean et al., 2009; Soukos et al., 2005) and Gram-positive bacteria (Ashkenazi et al., 2003; Enwemeka et al., 2009; Enwemeka et al The only logical explanation of Finsen's success is that endogenous porphyrins in tuberculosis bacteria absorbed the violet/blue light predominantly transmitted through his lamp system; the absorption triggered downstream production of reactive oxygen species, thus killing the bacteria and curing his patients of tuberculosis, not UV light This bacteria then produces a molecule that occurs naturally within the body called a porphyrin, which in turn kills the bacteria. The wavelengths used in blue light PBM are between 405 and 420 nanometers, different than the wavelengths used in ultraviolet light. We summarize studies investigating blue light or blue-red light for acne treatment in Table 2.[10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31] In general, high-intensity narrowband light (405–420 nm) applied for 8–20 min twice weekly for four weeks was reported to reduce inflammatory acne lesion count in the 60%–70% The wavelength of blue light has antimicrobial effects and kills Propionibacterium acnes, the most common type of bacteria that contributes to acne, according to Lindsey Bordone, MD, a board-certified dermatologist in the department of dermatology at Columbia University Medical Center in New York. A UV water purifier treats micro-biologically unsafe water with germicidal ultraviolet light. The UV wavelength scrambles the DNA of living organisms in the water so that they can no longer reproduce and make you sick. If you drink bacteria-infested water, the organisms can embed in your digestive tract and replicate. Ultraviolet radiation renders bacteria, viruses, parasites, and fungi unable .
