Moreover, UVC disinfection does not generate toxins or volatile organic compounds and does not require storage of hazardous materials. UVC disinfection relies on 250–280 nm wavelength radiation to inactivate pathogens as it penetrates microbial cells, disrupting DNA and affecting reproduction and survival [13,15] Read full study on UV-C disinfection HERE How UV-C disinfects: The UV-C wavelength band covers 100nm-280nm, and it directly overlaps with the peak absorption of DNA and RNA (∼260nm). The inactivation mechanism is straight-forward. Upon UV-C absorption, the pyrimidines in the RNA or DNA are converted to pyrimidine (6–4) pyrimidone photoproducts and cyclobutane pyrimidine dimers [10]. If the population of dimers is sufficiently high, transcription errors occur, ultimately resulting in inactivation of the bacteria or virus. As such, UV-C is a nearly universal disinfection method for bacteria, and its effectiveness in viral disinfection is not correlated with virus size, but with pyrimidine concentration. **To be effective the light must be able to reach the surface, so no stacking of tools, and no dirt, dander or hair because it blocks the light from reaching the surface somewhat. top drawer will get light from bottom, bottom drawer gets light from top. read article on effects of UV light on dust mites eggs here
