Leveraging Technology and Science

Method 1: Optimizing a Self-Sustaining Triboelectric Air Filter

Bacteria, germs and viruses come in many types and have many disparate characteristics.  The virus of greatest concern to us today is one that has been determined to carry a "gram-negative" electrical charge and  are "enveloped", meaning they have a outer protective membrane.  Although the virus is not a living thing in and of itself, it attaches to living "hosts" and hi-jacks them in order to survive.  Disabling them can be accomplished by penetrating the outer "capsid" and transferring a positive electrical charge to them (and essentially, electrocuting them). 

Technology Similar to the N95 Respirator  


While N95 respirators are considered by many to be the “gold standard” as it relates to face masks that are designed for medical personnel that it intended, designed and built to protect the wearer, what makes them effective is not widely known.  N95s are effective at viral filtration, capturing 95% of particlesas small as .3 microns.  While aerosolized viruses, including coronavirus-family microbes, are far smaller than .3 microns they don't travel alone: they hitch a ride on larger carriers that are caught by its barrier layers. Despite this, N95s actually filter smaller particles better than larger ones.  Nanosized particlesfall subject to the phenomenon of Browning Motion and are propelled at high speed in random directions.  In motion, negatively-charged microbes (e.g., coronaviruses) are attracted to the N95's positively-charged center layer. The viral microbe's gram-negative protein shell is deactivated by electrocution.


Creating a Self-Sustainable, Self-Powered Electrostatic Charge


Particle air filtration, in the form of a triboelectric air filter (TAF) can be created within the context of a fabric face mask through various design elements and the use of a combination of carefully selected textiles   These fabric combinations can create a tribo-electric air filter that is based on science that is similar to that that supports the electrostatic layer of an N95 device.  The TAF can attract a gram-negative  microbe, secure it and then transfer an electric charge to it, through its outer membrane, and electrocute or inactivate it.

 

The Stay Safer PRN95+ Protective Face Mask's design derives from our research and studies conducted by Stanford Medicine and a team of scientists from the University of Chicago and the world-renown Argonne National Laboratory* (the source of the exhibit at left).  This latter study found that cotton with silk or chiffon were the best combination of materials for fabric face masks as they help to create a triboelectric air filter to attract, secure and electrocute gram-negative microbials.  N95 respirators rely on electrostatic-like science. The data in the exhibit at right (provided by physicist/scientist Ron Kurtus) illustrates the charge differential between cotton and silk.   To "optimize" this design, our face mask has two center layers — each of silk chiffon — to amplify its friction-generating capability.  The mask is "recharged" daily by simply rubbing it by hand for twenty seconds .  Moreover, its design helps it be self-sustaining and self-powered by harnessing the aerodynamic friction created by the wearer's breathing to create abrasion between the layers

Method 2: Employing a Legendary Advancement in Chemistry

Again, as noted above, bad microbes come in many types and have many disparate characteristics.  Our present interest is focused on one that has been determined to carry a "gram-negative" electrical charge and  are "enveloped", meaning they have a outer protective membrane.   Disabling them can be accomplished by penetrating the outer "capsid" and transferring a positive electrical charge to them (and essentially, electrocuting them).  Whereas the triboelectric technology described above is a proven and effective method, this chemistry-based solution, which has been proven over four decades, leverage a chemistry-based means by which to create a positively-charged surface that attracts and then tranfers a fatal charge to gram-negative, enveloped microbes.


Both the outer and inner layers of the Stay Safer PRN95+ Protective Face Mask, and its ear straps, use fabric that has been treated with a powerful industry award-winning chemical antimicrobial that was originally created by Dow Chemical.  It is a quaternary ammonium compound (QAC), meaning it creates a chemical reaction on the surface upon which it is applied. It is also cationic, meaning it is positively charged and highly effective at inactivating enveloped microbes by stabbing their protein-based envelope (capsid or membrane) and electrocuting it. QACs inactivate enveloped microbes as a result of an electrical interaction between the ammonium active agent and the microbe’s negatively-charged cell membrane...and not poisoning.  

 

The product’ we use has an active ingredient called Dimethyloctadecyl (3-trimethoxysilylpropyl) Ammonium Chloride (DTSACl).  QACs, especially those that use DTSACl as their active ingredient, have been found to be highly effective against enveloped pathogenic microbes, whether they are germs, fungi, bacteria or viruses.  For a detailed discussion about Antimicrobial Testing Standards and Test Results, click here.
