Jul 10, 2023 · Here, to overcome this, we developed a novel method using UV-C light-emitting diodes connected to side-emitting optical fibres (SEOFs) placed directly on metal surfaces.

Oct 25, 2023 · This study introduces a technology using flexible side-emitting optical fibers (SEOFs) that are <550 μm in diameter and emit UV-C light along their entire length. The SEOFs are designed to fit into tubing with narrow diameters and …

This study now demonstrates its impact for disinfection of medically relevant organisms and introduces critical design calculations needed for its implementation. The flexible geometry and controlled emission of light in these UV-SEOFs make them ideal for …

Oct 1, 2022 · Thin and flexible nano-enabled side-emitting optical fibers (SEOFs) are novel light delivery devices that enable disinfection or photocatalytic oxidation by radiating UV light from light-emitting diodes (LEDs).

Ultraviolet, or UV, light offers an effective, chemical-free means of controlling this problem by damaging the DNA and enzyme repair systems of microbes—which leads to their demise.

Jul 10, 2023 · Introducing germicidal UV-C (200–280 nm) irradiation from light-emitting diodes (LEDs) into flexible side-emitting optical fibers (SEOFs) presents a novel light delivery method to inhibit the...

Jun 16, 2023 · Introducing germicidal UV-C (200−280 nm) irradiation from light-emitting diodes (LEDs) into flexible side-emitting optical fibers (SEOFs) presents a novel light delivery method to inhibit the accumulation of biofilms on surfaces found in …

Oct 1, 2020 · Attaching a SEOF to a single 265 nm light emitting diode (LED) increases irradiation area by >1000x and provides continuous low-irradiance of UV-C light to a large surface area. A zone-of-inhibition protocol was developed to quantify bacterial growth prevention on an agar plate around one SEOF.

amount of side-emitted UV-C light is overwhelmingly controlled by the evanescent wave energy interacting with nanoparticles at distances from < 2 to 100 nm from the surface of the optical fiber.

Silica nanoparticle coating on quartz optical fiber facilitates side-emission of germicidal ultraviolet light (UV-C), which shows promise for disinfection of contaminated air, water, and surfaces.
