Proven Science

Kills on Contact

NanoBio Protect is the only nasal skin antiseptic available that is alcohol-free, moisturizing, and proven in laboratory studies to kill 99.99% of germs that may cause infection.

Fast Acting and Effective

Innovative patented nano-droplets are physically drawn to germs to kill on contact, and can help reduce the risk of infection for 4+ hours.

Patented Technology

NanoBio Protect is a patented solution of oil-in-water nano-droplets that incorporate 0.13% benzalkonium chloride (BZK), a common skin antiseptic that has been used in humans for more than 75 years. Our proprietary formulation integrates BZK onto the surface of the nano-droplets, providing significant advantages in comparison to other skin antiseptics.


Studies demonstrate that topical NanoBio products are non-irritating and are not absorbed systemically.

Easy to Use

1. Use any cotton swab.

2. Apply to the skin inside and around each nostril.

3. Repeat every 4-8 hours as needed.


NanoBio Protect was developed by BlueWillow Biologics, a clinical-stage, biopharmaceutical company.
