AMETHYST: Advanced Microbial Eradication Through High-Intensity Yielding Sterilization Technology - A Multipurpose Decontamination Chamber Using 405 nm HINS Light

This paper presents the design and concept of a multipurpose decontamination chamber named AMETHYST (Advanced Microbial Eradication Through High-intensity Yielding Sterilization Technology), which serves as a cabinet for object decontamination and, with its outward-opening doors, can also effectively decontaminate an entire room. The development of this chamber is driven by the need for efficient and versatile decontamination solutions, particularly in response to the COVID-19 pandemic. The focus of this paper is to discuss various UV light techniques considered during the design process and the ultimate selection of 405 nm High Intensity Narrow Spectrum (HINS) light as the preferred wavelength. The proposed concept offers a flexible, cost-effective, and sustainable solution for achieving high levels of decontamination in both object and room environments.
