ROME, July 2 A United Nations-backed scientific research centre hasteamedupwith an Italian tech firm to explore whetherlaserlight can be used to kill coronavirusparticles suspended in the air and help keep indoor spaces safe.
The joint effort between the International Centre for Genetic Engineering and Biotechnology (ICGEB) of Trieste, a city in the north ofItaly, and the nearby Eltech K-Lasercompany, was launched last year as COVID-19 was battering the country.
They created a device that forces air through a sterilization chamber which contains alaserbeam filter that pulverizesviruses and bacteria.
I thoughtlasers were more for a shaman rather than a doctor but I have had to change my mind. The device proved able to kill theviruses in less than 50 milliseconds, said Serena Zacchigna, groupleader for Cardiovascular Biology at the ICGEB.
Healthy indoor environments with a substantially reduced pathogen count are deemed essential for public health in the post COVID-19 crisis, a respiratory infection which has caused more than four million deaths worldwide in barely 18 months.
Zacchigna hookedupwith Italian engineer Francesco Zanata, the founder of Eltech K-Laser, a firm specialised in medicallasers whose products are used by sports stars to treat muscle inflammation and fractures.
Some experts have warned against the possible pitfalls of using light-based technologies to attack thevirusthat causes COVID-19.
A study published by the Journal of Photochemistry & Photobiology in November 2020 highlighted concerns ranging from potential cancer risks to the cost of expensive light sources.
But Zacchigna and Zanata dismissed any health issues, saying thelasernever comes into contact with human skin.
Our device uses nature against nature. It is 100% safe for people and almost fully recyclable, Zanata told Reuters.
The technology, however, does not eliminateviruses and bacteria when they drop from the air onto surfaces or the floor. Nor can it prevent direct contagion when someone who is infected sneezes or talks loudly in the proximity of someone else.
Eltech K-Laserhas received a patent from Italian authorities and is seeking to extend this globally.
The portable version of the invention is some 1.8 metres (5.9 ft) high and weighs about 55 lb. The company said the technology can also be placed within air-conditioning units.
In the meantime, the first potential customers are liningup, including Germanys EcoCare, a service provider of testing and vaccination solutions.
The company aims to license the technology for German and UAE markets, an EcoCare spokesperson said in an email to Reuters.
