Korean scientists develop first photothermal filters that kill coronavirus

KOREA HERALD – South Korean scientists have developed the world’s first photothermal-effect-based high efficiency particulate air filter – also known as HEPA filter – that can take out 99.9 per cent of influenza and COVID-19 viruses, the Korea Institute of Energy Research said on Tuesday.

The photothermal effect, which refers to the mechanism of how a substance absorbs light energy and turns it into heat energy, is used in various areas such as drug delivery, cell death, sensor and solar battery.

The research team came up with the technology to manufacture photothermal HEPA filters by coating the existing HEPA filters with plasmonic metal nanoparticles that produce photothermal effects.
