NoEM Paint – Protection against SARS-CoV-2 in confined spaces

Infection with the virus can occur through droplets through direct contact with the virus carrier.
When a sick person coughs, talks, sneezes or simply exhales, the virus contained within aerosols
(tiny droplets) is inhaled by people nearby. The exhaled aerosol settles upon various surfaces from
which, by simply touching by hand, the virus can be transferred to the area of the nose, mouth or
eyes and thus lead to infection.

Over 7 years ago, nanotechnology specialists developed the NoEM Electro Protector paint. The  paint, after being applied to a porous surface where thermodynamic conditions are established (temperature, pressure and humidity), is a composite that shows high dielectric absorption related  to dielectric and electrical inhomogeneity. The absorption frequency band can be adjusted to the  application requirements by changing the composite component phases, their volume ratios and the  method of connecting the phases. It is an innovation in the field of technology, which through the  appropriate selection of components, reacts to the change in air humidity in a room and “pulls” the  aerosol with viruses through the surface of the wall until the humidity in the wall is in equilibrium  with the humidity in the room. 

To check whether a wall painted with NoEM Electro Protector can inactivate SARS-CoV-2 viruses, the  virology laboratory ProChimia Surfaces Sp. z o.o. conducted a series of experiments. To analyse the  effectiveness of viral particle inactivation, the reference virus BHV-1 was used, which, like SARS CoV 2, is an enveloped virus, which determines its resistance to virucides. 

The aim of the study was to assess the effectiveness of inactivation of viral particles by analysing Noem paint samples on substrates made of polystyrene plates with a diameter of 6 cm, during: 10  minute, 100 minute and 24 hour periods. The methodology was based on the guidelines contained  in the ISO 21702 measurement of antiviral activity on plastics and other non-porous surfaces. 

The ability of the test product to inactivate the test virus BHV-1 was determined on the basis of the  reduction of its infectious titer, caused by contact with the test material. The standard criterion for  the virucidal activity of the test product against a given virus is a reduction in the titer of infectious  virus after 24 hours of incubation by at least 2 logs. NoEM Electro Protector paint after 100 minutes  of incubation with a viral lysate reduces its infectious titer compared by more than 2 logs, and after  

24 hours of incubation, the decrease in infectious virus titer is almost 4 logs compared to the  control, which is about 99.99 %.

In conclusion the study showed the great virucidal potential of NoEM paint with a recommendation  for certification. 

Summary 

According to an expert from ADR System, the virucidal action of NoEM Electro Protector is usually  connected with the photocatalytic effect of titanium oxide. However, the proven effectiveness of  NoEM Electro Protector in comparison to the effectiveness of other paints containing TiO2, is related  to another cause. NoEM Electro Protector paint, after being applied is a composite, where the  greatest share in the regulation of humidity and the determination of thermodynamic conditions is  salt, which forms hydrates (reversible, with varying degrees of hydration). In this case It is the  electric field of the space charge in the composite that has a virucidal nature. This may also be  contributed to by the mixed valence of the titanium. 

The composites used are reserved in international patents. Patents have been granted in 23  countries, including most of Europe, Canada, Brazil, USA and China. 

Comments 

– The walls of a closed room painted with NoEM Electro Protector paint do not change their  properties over time, do not require additional energy expenditure or special maintenance (apart  from removing ordinary dirt). They provide additional protection against viral infection for people  staying in these rooms (e.g. classrooms, hospitals, health centres, churches, exhibition halls,  cinemas, theatres or apartments). 

– According to recent reports, the survival time of the Omicron mutation is much longer than that of  other COVID-19 mutations (about 8 days on plastic and over 21 hours on skin). Therefore, any new  protective option is important. NoEM paint, the cost and application of which does not differ from  ordinary paints, is an excellent example of the potential for this new technology. 

– NoEM Electro Protector is the first paint that, when applied to a wall, forms a barrier against an  alternating electric field due to a mechanism related to the high dielectric loss of the composite. It  permits the constant natural electric field of the earth, it is not a Faraday cage, it does not require  

grounding, it is composed in such a way that it does not interfere with information signals carried by  RF, Wi-Fi type (2.5 GHz). 

Interested companies producing paints, impregnations, roofing membranes, underlays for flooring  and well as other products this invention can also be implemented, can apply to the inventor, Dr. Eng. Stanisław Wosiński from ADR System, in order to implement such products on the market. You  can read more about the operation of this technology on the websites: www.adr.com.pl www.noem.co 

About the inventor 

Dr. Eng. Stanisław Wosiński is a Polish scientist, laureate of many prestigious international awards,  including the Marie Curie Skłodowska Medal awarded once a year on the anniversary of the  discovery of polonium and radium and the Gold Medal in the field of Environmental Protection and  Energy at the Geneva International Exhibition of Inventions. He obtained a PhD in technical  sciences in the discipline of: materials engineering, specializing in dielectric materials, solid state  physics. His doctoral dissertation concerned the influence of the composition and production  conditions of ceramics and polymer composites upon the screening ability of alternating electric  field.
