Osram invests in UV LED specialist Bolb Inc.

Currently, the majority of UV-C disinfection applications are based on conventional lighting technologies, usually mercury vapor lamps. Compared to these traditional lamps, UV-C LED technology has the potential to consume significantly less energy, while still providing the high light output required. The collaboration between Osram and Bolb promises to overcome this technological hurdle. Thanks toContinue reading “Osram invests in UV LED specialist Bolb Inc.”

Robots are disinfecting hotels during the pandemic. It’s the tip of a hospitality revolution.

https://www.washingtonpost.com/travel/2021/01/27/hotels-robots-cleaning-hospitality-covid/ “The cleaning routines at most busy airports and hotels had remained relatively unchanged for decades. But as the pandemic rages into its second year, major brands are increasingly turning to the world of high-tech disinfection to strengthen their cleaning protocols. It’s a trend that’s slowly transforming housekeeping — and accelerating the pace of automationContinue reading “Robots are disinfecting hotels during the pandemic.

Existing UV light technology has potential to reduce COVID-19 transmission indoors

A recent study has shown that a UV light technology already used to prevent the spread of other airborne diseases in buildings has the potential to be effective against COVID-19. The research, published in the journal PeerJ, found that upper room UV germicidal irradiation (UVGI) can kill SARS-CoV-2 virus particles, which can be transmitted by aerosolisedContinue reading “Existing UV light technology has potential to reduce COVID-19 transmission indoors”

More on: Does UV-C Kill SARS-CoV-2?

Does UV-C Kill SARS-CoV-2? Yes. SARS-CoV-2 being a relatively new virus (hence ‘novel’) there are not yet 100’s of proper scientific papers confirming this, BUT on top of indeed 100’s that confirm efficacy against various Corona viruses, there are a growing number that look specifically at SARS-CoV-2: https://www.ajicjournal.org/article/S0196-6553(20)30756-2/fulltext Susceptibility of SARS-CoV-2 to UV irradiation MostContinue reading “More on: Does UV-C Kill SARS-CoV-2?”

Light-based technologies for management of COVID-19 pandemic crisis

From Science Direct, Nov 2020 https://www.sciencedirect.com/science/article/pii/S1011134420304498 Highlights Light-based technologies currently are cost-effective and widely available in market.• Photons can be used to inactivate SARS-CoV-2 in air, liquids and on surfaces.• Phototherapy can be used as an adjuvant to control virus infection and to modulate host immune system.• Light-based solutions can significantly contribute to mitigate theContinue reading “Light-based technologies for management of COVID-19 pandemic crisis”

How long the virus can survive

Transmission of SARS-CoV-2 via surfaces The role of transmission of SARS-CoV-2, the virus that causes COVID-19, by touching contaminated surfaces is not yet fully understood.Enlarge image Droplets of SARS-CoV-2 in artificial mucous were applied to test surfaces. The work is being done within our highly secure Biosecurity Level 4 laboratories at the Australian Centre forContinue reading “How long the virus can survive”

Virus that causes Covid-19 can survive up to 28 days on surfaces, scientists find

https://www.theguardian.com/world/2020/oct/12/virus-that-causes-covid-19-can-survive-up-to-28-days-on-surfaces-scientists-find Australian scientists have found that the virus that causes Covid-19 can survive for up to 28 days on surfaces such as the glass on mobile phones, stainless steel, vinyl and paper banknotes. The national science agency, the CSIRO, said the research undertaken at the Australian Centre for Disease Preparedness (ACDP) in Geelong also found thatContinue reading “Virus that causes Covid-19 can survive up to 28 days on surfaces, scientists find”
