The antimicrobial impact of visible violet and blue light has been known for more than a century but hardly been applied for purposeful pathogen reduction or prevention. The disinfecting properties of wide-spread warm-white and cool-white light emitting diodes (LEDs) are investigated by irradiation of staphylococci with different LEDs and varying doses. Additionally, the combination of a white and a violet LED illumination is examined. Both white LEDs exhibit an antimicrobial effect, which…

High Intensity Violet Light (405 nm) Inactivates Coronaviruses in Phosphate Buffered Saline (PBS) and on Surfaces

It can be concluded that 405 nm irradiation has an antiviral effect on coronaviruses, but special attention should be paid to the presence of photosensitizers in the virus environment in future experiments.

Development of an antimicrobial blended white LED system containing pulsed 405nm LEDs for decontamination applications

This study details the design, build and testing of a prototype antimicrobial blended white light unit containing pulsed red, yellow, green and 405nm LEDs. With a push for alternative methods of

Visible optical radiation generates bactericidal effect applicable for inactivation of health care associated germs demonstrated by inactivation of E. coli and B. subtilis using 405-nm and 460-nm light emitting diodes

The employed optical setup, which delivered a homogeneous illumination and skirts the need of a stirring technique to compensate irregularities, was an important improvement compared to previous published setups.

Photoinactivation of bacteria by endogenous photosensitizers and exposure to visible light of different wavelengths – a review on existing data

This review compiles the published data on bacterial inactivation caused by visible light and endogenous photosensitizers and evaluates more than 50 published studies containing information on about 40 different bacterial species irradiated within the spectral range from 380 to 780 nm.

High-intensity narrow-spectrum light inactivation and wavelength sensitivity of Staphylococcus aureus.

It was found that inactivation of S. aureus occurs upon exposure to blue light of wavelengths between 400 and 420 nm, with maximum inactivation occurring at 405+/-5 nm, which emphasises the potential of exploiting these non-UV wavelengths for disinfection applications.

Potential self‐disinfection capacity of touch screen displays

To test the antimicrobial capacity of touch screen displays, Staphylococcus carnosus is distributed on Samsung tablets and illuminated for up to 36 hours, with white light being the most efficient followed by blue, green and red light.

Inactivation Effect of Violet and Blue Light on ESKAPE Pathogens and Closely Related Non-pathogenic Bacterial Species – A Promising Tool Against Antibiotic-Sensitive and Antibiotic-Resistant Microorganisms

Visible light irradiation is a promising approach to inactivate ESKAPE pathogens with future fields of application in prevention and therapy.

In vitro bactericidal effects of 405-nm and 470-nm blue light.

In vitro results indicate that, in vitro, 405- and 470-nm blue light produce dose dependent bactericidal effects on Pseudomonas aeruginosa and Staphylococcus aureus but not Propionibacterium acnes.
