一种有前途的物理原理是用UVC光照射,可用于破坏微生物而不会产生抗性。 In Germany, between 400000 and 600000 hospital bacterial infections occur each year - about 10000 to 20000 people die. Since multidrug-resistant (MDR) pathogens are usually not treated with antibiotics, other methods are needed. ...
Air purifiers with UV bactericidal functions are generally safe for humans, but there are some key factors to be aware of to ensure that it does not pose a potential health hazard. Ultraviolet sterilization mainly relies on UVC band (200-280nm) ultraviolet light to kill bacteria, viruses, ...
Brenner found out that a narrow band of UV light called far-UVC light cannot penetrate skin living cells. “That’s why it’s safe for human exposure,” said Brenner. Earlier, Brenner’s team has already tested two types of coronaviruses and is currently testing SARS-CoV-2. “We sa...
UV-C light iscommonly used to clean surfacesbut is not safe for humans and animals in extended amounts. High-energy visible light, or HEV light, has no harmful effect on humans or animals and doesn’t require protective equipment to use. However, it takes longer to disinfect. While HEV ...
(1)细节理解题。根据第二段The bandage has small LED bulbs that produce a type of high-energy light called ultraviolet-C(UVC) when it is UVC to sterilize wounds has been a challenge because it requires a source of energy.(这种绷带有小型LED灯泡,当紫外
It's well established UV radiation iscarcinogenic(causes cancer) for humans. Devices that emit UVC should be calibrated to ensure optimal microbial killing power and are more effective when placed close to the surface or object being treated. When turned off, UVC emissionis halted, too. ...
Security and surveillance systems demand high-quality images even in extremely low-light environments. UVC cameras equipped with CMOS sensors offer superior low-light sensitivity, while the USB 3.0 interface supplies the necessary power for their operation. ...

Limited data in humans have revealed that resveratrol is pharmacologically safe. As a nutraceutical, resveratrol is commercially available in the USA and Europe in 50 µg to 60 mg doses. Currently, structural analogues of resveratrol with improved bioavailability are being pursued as potential ...
The light emitted by the sun consists of three frequency bands of radiation: infrared, visible, and ultraviolet. Of the three, only the ultraviolet is harmful to most humans. Ultraviolet (UV) radiation is further divided into three categories: UVA, UVB, and UVC. UVA radiation penetrates the ...
