Everyone infected with a life-threatening pathogen deserves a treatment.

Using light to treat COVID-19.

EmitBio is a life science company developing breakthrough medical devices that change how the world treats respiratory infectious disease.

EmitBio has discovered how to use precise, monochromatic wavelengths of non-UV light to eliminate invading pathogens and stimulate host defense in the body — effectively creating an antiviral environment.

Where Light meets Life™.

Your body is under attack every day.

Every breath including life-giving oxygen is accompanied by a host of other microorganisms, some harmless, others potentially life threatening. The ones that threaten us are called pathogens and include:



Causing COVID-19, SARS, MERS, Flu, Measles, Whooping Cough, the Common Cold



Causing Tuberculosis, Bacterial Pneumonia, Meningitis, Diphtheria

Our light therapy shows the potential to defeat them all.

While developing light-based treatments to fight the global SARS-CoV-2 pandemic, we made a novel discovery—the treatments were also effective in fighting other pathogenic infections, such as, bacteria, influenza viruses, cold viruses, and many more.

Universal Antiviral

This discovery puts forth the promise of an effective, non-pharmacological treatment for a wide variety of pathogens. While additional and specific clinic trials for other pathogens are needed to 100% confirm our findings, the in-vitro demonstration of efficacy against a spectrum of pathogens that promises the potential of a “universal antiviral” is in reach.

Our Mission: Change how the world treats infectious disease.

  • Develop advanced LED technology to produce the desired therapeutic and protective outcomes.
  • Deliver market-ready products for clinical and home use.

The promise of light-based antiviral therapies from EmitBio:

  • Uses safe, visible spectrum light, to treat respiratory illness.
  • A non-pharmacological treatment, no chemicals or pills with adverse side effects.
  • Mechanism of action not dependent on viral makeup or configuration of spike protein leading to utility as a treatment for current mutations and/or future genetic drift.

The EmitBio Leadership team

Our leadership team represents decades of research, discovery and development in both life science and light science. The therapeutic applications of this fusion of light science and life science are limitless.
