  1. How UV Light Works in the Fight against Viruses like COVID-19? In the fight against COVID-19, an old weapon has re-emerged. Ultraviolet (UV) light disinfection is getting popularity as a method for disinfecting hospital rooms and other public spaces. For decades, scientists have known about the disinfection capabilities of ultraviolet (UV) light. The main benefit is its ability to kill germs like viruses and bacteria and is considered an important tool in the fight against COVID-19. The use of UV-based disinfectants like UV Robots has seen a sharp rise during this pandemic. These devices use Ultraviolet C (UVC) radiations to disinfect items and help keep public places clean and safe In this article, let’s explore how UV light is used to kill bacteria and how helpful it is at eliminating the new coronavirus. Does all UV light kill germs? There are various types of UV light and are classified according to how much energy they have. Types of UV light UV-A light has an extremely low amount of energy. These rays hit the earth's surface from the sun. We are exposed to UVA light when we are out in the sun. Its exposure could lead to skin aging and damage. UV-B light lies in the middle of the UV light spectrum. A small portion of sunlight contains UV-B light, and its exposure could lead to sunburns and skin cancers. UV-C light has the highest amount of energy. We are normally not exposed to UVC light daily, as it is mostly absorbed in the Earth’s ozone. However, there are various man- made sources of UVC light. This type of UV light is highly effective in killing germs and can be used to disinfect surfaces, air, and liquids. UV-C Light helps in reducing the spread of infectious diseases and other harmful microorganisms. It works by breaking down the DNA structure of the bacteria and viruses, damaging molecules like nucleic acids and proteins and stopping them from multiplying.

  2. Someknown Facts about UVC light and the new coronavirus Let’s look at what the research has discovered about UV-C light and the new coronavirus, SARS- CoV-2 so far. UV-C light for disinfecting liquids A recent study published by The American Journal of Infection Control (AJIC), uses UVC light to kill large amounts of the new coronavirus in liquid cultures and found that exposure to UVC light completely inactivated the virus in 9 minutes. UV-C light for disinfecting surfaces Another study, found in the AJIC, examined using a specific type of UVC light to kill SARS-CoV-2 on laboratory surfaces. The study reveals that the UVC light damaged the live coronavirus by 99.7 percent in 30 seconds. The type of UVC light used in this study is between the wavelengths of 207 and 222 nanometers and is called Far-UVC light. Far-UVC light is less hazardous to human skin and eyes than other types of UVC light. UV-C light for disinfecting the air One study, found in the Scientific Reports, investigated using Far-UVC light to kill two types of human coronaviruses, 229E and OC43 in the air. These viruses can cause the common cold in humans. Based on this research, it is estimated that far-UVC light could kill 99.9 percent of airborne coronaviruses in about 25 minutes. Abstract These findings show that UVC light can effectively kill viruses in liquids, on surfaces, or in the air and can be a good option for disinfection. How UVC light is currently used to kill the new coronavirus? Because it presents less health hazard to humans and can effectively inactivate the new coronavirus without using chemicals, UVC light becomes an attractive option for disinfection. Special lamps using robots that emit UVC light are typically used for this purpose.

  3. Because of its high frequency, UV-C Light is very damaging to bacteria and viruses. The UV light will effectively damage the DNA or RNA code of the Pathogens, and cause lethal mutations that prevent them from reproducing. Innovation in UV-C Light Disinfection Various companies are developing innovative technologies and focus on automation of the UV- C light disinfection process using robots. Using UV Robots has many added benefits over conventional cleaning including speed, reliability, and reporting of each room cleaned with no use of chemicals. UV Light-emitting robots are excellent at hospitals, airports, hotels, and other crowded places making cleaning and sanitizing more efficient and quicker. There are many companies that are selling and hiring UV Disinfection Robots that can kill 99.99 percent of SARS-CoV-2 viral particles in 2 minutes. All this has seen increased demand and in the future, it is likely that robots like this could be used for disinfection of hospital rooms, hotel rooms, schools, office buildings, and airplanes.
