Stop the next pandemic - Permanent Silver Invisible Ink Disinfectant

I posted this on LinkedIn today, I hope nobody minds posting it again here.
. Please share – it would be great to make an antiviral go viral. :microbe: :smile:

Permanent Silver Invisible Ink Disinfectant

We Can Stop the Next Pandemic

September 2, 2024

Introducing Permanent Silver Invisible Ink Disinfectant (PSII-D, pronounced “psi-dee”): a breakthrough permanent antimicrobial solution that can be easily applied to any surface, even cloth, to stop the spread of infections and prevent pandemics. The product creates an invisible layer of antimicrobial silver that binds to any surface, providing long-lasting protection against bacteria, viruses, fungi and other microorganisms for a cost to customers of less than ten cents per square meter.

Technical / Operational Overview

The solution is based on a combination of natural tannic acid and silver, which forms an invisibly-thin film that permanently bonds to surfaces. Like the “varnish” that accumulates in teapots, or the ancient permanent ink on which it is based, PSII-D is resistant to wear, water and other environmental factors, ensuring long-lasting effectiveness.

PSII-D can be applied to any material that can tolerate brief exposure to water. It can be applied by wiping, spray or immersion by cleaning staff with minimal training. It reaches a thickness of about 25 – 50 atoms instantly. Its thickness remains consistent regardless of how long the solution is applied. Its presence can be verified using a simple field test. It can be removed with bleach or other chemicals, such as hydrogen peroxide.

Its ingredients are natural and safe: tannic acid is found in the leaves, bark and fruits of many plants and is often consumed in food and drink; silver drops were widely used in newborn babies’ eyes at over 100 times the concentration used in PSII-D.

Markets

The potential market for Permanent Silver Invisible Ink Disinfectant is huge, with applications in many industries:

  • Healthcare: Infection control in hospitals, clinics, and nursing homes, particularly for laundry
  • Hospitality: Sanitizing surfaces in hotels, restaurants, and other public spaces
  • Education: Cleaning and disinfecting school environments, including classrooms, cafeterias, and locker rooms
  • Public Health: Stockpiling for pandemic preparedness
  • Agriculture: Preventing bird flu in poultry farms and other livestock facilities
  • Filtration: makes water and air filtration media permanently antimicrobial
  • Food Handling: Sanitizing plates, utensils, cutting boards, and food processing equipment in restaurants and food production facilities
  • Real Estate: Preventing mold growth and maintaining a clean environment in residential and commercial buildings
  • Packaging: Inhibiting spoiling in packaged food and drink

Market Size and Growth

Effective, permanent, non-toxic antimicrobial treatments are a new market which should grow to at least $5 billion in the next few years. I anticipate that PSII-D will capture a significant share of this market, with a projected revenue of up to $500 million within the first five years. The business model is to market primarily to businesses and institutions.

Costs and Production

Cost of production is low: the cost of materials is less than a penny per square meter, plus packaging. Selling concentrated solution in bulk cuts shipping costs and makes PSII-D extremely affordable for institutions: about $1/L, under $0.05 per square meter, while maintaining a high profit margin (~14x over cost of materials).

For retail customers, costs will still be quite affordable: $2 – $20 per liter. One liter should cover 20 – 100 square meters.

Investment Opportunity

Actuway is seeking investment to scale up production, establish a distribution network, and expand marketing efforts to bring this innovative permanent antimicrobial solution to market.

Conclusion

With your help, Permanent Silver Invisible Ink Disinfectant can stop the next pandemic. With its proven permanent antimicrobial properties, wide range of applications, and inexpensive production, this product will create a new, multi-billion dollar global market, prevent billions of illnesses and save millions of lives over the coming decades. I’m looking for potential investors, partners and employees to help bring this revolutionary product to market.

Disclosure: Actuway is, as of Sept. 2, 2024, an unincorporated pre-seed startup with no sales, one employee (me) and an undetermined valuation. This is not an offer to sell securities. This is not an offer to buy or sell any product, service, or anything else (though I’m open to negotiating potential contracts in accordance with all applicable laws and regulations). All valid rights reserved. A cursory search reveals no issued patents on this; the one provisional patent application appears to be unlikely to issue and the assignee appears to no longer be in business. I believe there is prior art invalidating the validity of any broad patent on silver + tannic-acid surface treatments, but there may be a risk of intellectual property disputes.

How would you compare your solution to Microban solutions.

Thanks for bringing Microban up. They have many different lines of products, but in general they’re additives for plastics and textile manufacturers, they are built-in rather than applied, they seem likely to often be more toxic before the polymer cures, they may use particles (though not nanoparticles) and they are much more expensive. Their Silver Shield product is the most directly comparable to PSII-D. It uses ionic silver which leaches out, (they claim it doesn’t, but they also say it’s “released”), is less effective and more toxic than ground-state silver.

  • PSII-D is safe enough to drink (though not for your gut biota; tannic acid is GRAS in the US and not considered an additive in the EU),
  • it can be applied to anything long after manufacture by cleaning staff with minimal training,
  • it is insensitive to temperature or duration of application, has no process parameters to monitor,
  • it uses ground-state silver which is completely chelated by the tannic acid (it seems that this is one of the main functions of TA in plants), so it doesn’t leach out, and is more evenly dispersed in the coating and
  • it’s much, much cheaper.

That said, I need to do more research on their products and test them head-to-head.

Here’s a chart of PSII-D effectiveness against viruses vs. other metals in TA coatings on silk:


As you can see, TA by itself has some effectiveness, but other metals don’t do much at all compared with silver.

I posted details earlier in another thread: Inventions and attempted inventions - #4 by Enon

I’ll give some key bits from the paper cited there:

after incubation with E. coli, the Ag/TA-coated textile and uncoated textile were left to sit in LB growth media overnight, and the OD600 of the uncoated textile (high turbidity) was at least 2-log [100x] higher than that of the Ag/TA-coated textile(transparent), with OD600 values of 26.6 vs 0.1 for paper, 2.21 vs 0.01 for silk, and 27.3 vs 0.27 for polyester, respectively

This was a test measuring the number of bacteria in a growth medium by the scattering or turbidity of the medium after the bacteria incubated overnight.
