UH Facilities Using New Technology Developed by UH Physicist to Fight COVID-19

Capture Coating in different sizes

Water beading on air filter coated with Capture Coating

The Facilities/Construction Management Preventive Maintenance team is implementing a new nanotech coating, called Capture Coating, developed at the University of Houston by Seamus Curran, professor of physics.

This coating will improve the ability of air filters to trap the coronavirus that causes the COVID-19 illness. It was developed at UH's Technology Bridge by Curran Biotech. 

Facilities/Construction Management is working to install this new technology in all buildings that have less than MERV-13 rated filters in time for the Fall 2021 academic semester. The MERV rating system reflects a filter’s ability to capture particles of varying sizes.

Facilities Preventive Maintenance Using New Technology to Fight COVID-19

The Facilities/Construction Management Preventive Maintenance team is implementing a newly developed nano-coating technology, called Capture Coating, developed at the University of Houston. This coating will improve the ability of air filters to trap the Corona virus that causes the COVID-19 illness and was developed at UH's Technology Bridge by Curran Biotech.

Curran Biotech's new nanocoating could prevent indoor transmission of COVID-19

A new nanocoating from Curran Biotech could dramatically improve air filtration to prevent the spread of COVID-19 indoors.

Their Capture Coating technology acts as a supplement to any household or commercial HVAC system by bonding to the filter fibers, giving them greater hydrophobic properties. This combined effect prevents virus-carrying droplets from traveling through the filter fibers, which, without the treatment, only prevent some viral transmission.

“ ‘Capture Coating’ is designed to mitigate and significantly decrease viral transmission of COVID-19 through specified air filtration media by forming a breathable, flexible, non-leaching, water-repellent barrier against aqueous respiratory droplets that act as virion carriers that can potentially be recirculated through conventional air-filters,” wrote Curran Biotech founder and University of Houston physics professor Shay Curran in an email. Despite the molecular complexity of the coating, the product itself can simply be sprayed onto an HVAC system’s filter.
