Disinfecting Nasal Sprays

The Fend Nasal Spray Reduces the Number of Respiratory Droplets

— November 8, 2021 — Lifestyle
The Fend nasal spray is designed to reduce the number of respiratory droplets the user breaths out by approximately 99%. Invented by Dr. David Edwards, an aerosol physicist, the spray aims to fight against airborne pathogens. A single spritz of Fend's liquid stabilizes the mucus in the nose to ensure the user is less likely to exhale droplets. It also traps inhaled droplets, so they don't make their way to the lungs.

Currently, Fend is in its clinal trials. The spray is made from a special solution of saltwater fortified with calcium. The formula hydrates the mucus layer in the respiratory airway, which is the body's natural defense system against pathogens. Users administer the spray through a pocket-sized bottle designed by San Francisco-based design firm Ammunition.
