Nasal Photodisinfection COVID Study

We’re looking for people to participate in our research study investigating whether a form of light therapy called photodisinfection can decrease the number of coronavirus particles present in the front part of the nose.

What is photodisinfection?

Photodisinfection (PDF) is a technology that is currently used in some hospitals before surgery to lower the risk of infection after surgery. PDF uses light waves and a gel/liquid photosensitizer. A photosensitizer is a molecule that disrupts other molecules, to kill bacteria and viruses.

Who can participate in the study?

You may be eligible to participate if you have recently tested positive for COVID-19.

What’s involved in the study?

During your study visit:

  • Swabs will be taken of the inside and front part of your nose.
  • The photodisinfection light therapy will be applied.
  • Repeat swabs will be taken of the inside and front part of your nose.
