'COVAIR': Is SARS-CoV-2 airborne and does it interact with particle pollutants?

UKRI Engineering and Physical Science Research Council (EPSRC) logo

Funded by the EPSRC under the Covid-19 call, COVAIR wish to develop diagnostic tools and predictive sensing to detect SARS-CoV2 in crowded urban environments in order to address whether the airborne amounts are high enough to cause a respiratory infection and whether pollution particles can carry live virus that is directly inhaled into the lungs. We will determine whether SARS-CoV2 can be detected as an active virus in the air of hospitals with Covid-19 patients, and if so, use a similar technique to measure the virus in crowded spaces such as in underground train platforms, central station concourse, shopping malls and busy roadside.

  • Duration: January 2021 – December 2021
  • Total value: £582,000
  • Co-I and Surrey PI: Professor Prashant Kumar (UoS) | Professor Fan Chung (Lead PI; Imperial College London, ICL) | Professor Chris Pain (Co-I; ICL) | Professor Alex Porter (Co-I; ICL) | Professor Ian Adcock (Co-I, ICL) | Dr Pankaj K Bhavsar (Co-I; ICL) | Claire Dilliway (Project Manager, ICL).

Globalhome logo

GlobalHOM is currently developing a disruptive innovation aiming to provide affordable, environmentally sustainable, flexible, modular housing with a built-in ‘Smart Home’ technological platform and associated hardware at the core of their design. It is worth noting that the approach GlobalHOM has taken to conceptualise and develop their offering is based on an end-user-centric approach, more akin to consumer product design than a construction industry approach whereby innovations typically focus on cost/time saving benefits for the construction industry stakeholders rather than the end-user.

Funded by UK Research and Innovation under the Innovate UK (Feb 2019 - Jan 2020).
