Aerosols should be avoided and are the worst thing you can use for particles that small. It's like hitting the particles with a hurricane. The aerosol (generally a spray can) will push the particles ahead or to the side of the spray area. There is also the possibility of making the situation worse by providing lift to the virus particles and keeping them airborne longer.
Cheap bottle pump-action sprayers used for watering plants or washing windows or spray perfume bottles provide better atomizing at a much lower velocity. This will also give better coverage as well as easy availability.
Most importantly, it provides a secondary engineered barrier that presents no logistical problems to implement. Populations can implement this easily. And this could be done immediately.
Experiment to validate usage for COVID-19
An experiment to prove the value needed for acceptance would only require a small enclosed measurable space like a glovebox. This would consist of a small enclosed measurable space where non-COVID (safe) .11 micron-sized positive charged particles (+) can be dispersed roughly to make sure a known quantity of particles are airborne.
The particle concentration would be measured at the beginning with air measuring devices equipped for .11 microns. . A method to disperse surfactant through a pump sprayer is necessary, such as via gloves attached to the container or other methods.
Inside the contained area the surfactant mix is atomized and dispersed. Household detergents mixed with water such as used for dishes are surfactants could be tested for efficacy because most are anionic (-) surfactants to get the mix correct. It would be proportionately small like 100 to 1.
The point is to use what people already have and work the problem without everyday people having to spend more money they can't spare.
This anionic surfactant in dishwashing and laundry detergent mixed with water will attract COVID-19 particles like a magnet when atomized, neutralize them, and take them to the floor surface.
Other types of surfactants (+positive charge) will repel the virus particles and keep them in front of sprayed areas doing little to nothing or even aggravating the situation because the same poles of a magnet repel each other (+)(+) which will increase virus hang time in the air.
Upsides and Downsides of this methodology
It will create a climate where populations will be disinfecting the world around them as they go and their own work environments proactively. Whether it is in the office, doing errands, or at home, it will give people the opportunity to mitigate the risk of contagion if they find themselves in a high-risk situation for contagion or they are in a high risk demographic.
The method uses products that are not harmful to people and are environmentally safe. It reduces the need to rely on government resources by putting tools directly in their possession. Everything needed is already in hand for most people.
The downside is if it creates a sense of complacency or invulnerability to the virus ie not wearing masks or observing social distancing. Or worse, not following medical advice as the situation develops.
Lastly, the method leaves a soap residue with the dead virus the surfactant collects. While harmless, it will need to be wiped down.
