The spray works by forming a protective coating (a gel-like matrix) on the nasal cavity, which captures airborne respiratory droplets and acts as a physical barrier against viruses and bacteria, while effectively neutralizing them. This gel doesn't affect the user's breathing.

Experiments in mice showed that a single dose of the PCANS nasal spray could effectively block infection from an influenza virus (PR8) at 25 times the lethal dose. Virus levels in the lungs were reduced by >99.99 percent, and the inflammatory cells and cytokines in the lungs of

Obvs this is still in progress and has only been tested on mice, but do we have guesses on how such a gel spray would stand up to sneezing and general nose blowing? (I saw your addition on possible future testing for allergens and am excited by the thought!)

I wonder if it is effective against allergens like mold or pollen. Big market there!

do you think some user who isn't me woudl still be able to do coke if they sprayed before heading out for the night
