@Oatcake. @Simmo222. Thank you both for your interest and putting some research into MWG. I will do my best to answer the questions you raised and also I will paste what I posted earlier today on the SKIN board to perhaps help you and others interested where we are right now. Nothing I am putting here is material and merely expands on existing Regulatory and REACH RNS's that are in the public domain.
Part of the reason it has been necessary to take samples, bring them back to the laboratory, convert RNA to DNA and run PCR tests is because of the concentration of the virus required and the matching of the genetic code to verify the results. This can take many hours, but in reality at least a day, possibly 3, depending on how many tests and the steps taken. Nothing wrong with that, just time.
The biggest problem is that the virus is roughly 120nm-150nm where 1 millimetre = 1 million nano-meters. It's like looking for a very specific needle in a haystack, in giant field of haystacks. So what we have to do is a) capture the target pathogen and b) confirm that we have actually captured something and then c) find a way to confirm that we have actually captured the specific target we were looking for. Remember we are looking for something that is 1/7000th the thickness of 1 millimetre.
Let's say we have the ability to capture a single target in wastewater (see the animated microfluidic video on twitter https://twitter.com/gjbrandon/status/1266028826557022210?s=20) because we use a technique that is designed specifically to capture the target bound to a silicon wafer (as used in the production of AMD or Intel microprocessors) that is 1/10000 of a millimetre thick on a plate of glass. As the water flows over the surface of the silicon wafer any virus that have passed through a filter is attracted to the binding agents on the wafer.
Now we use a proprietary technique to enhance the digital signal of the contact of the target using nano-photonics (nano-optics) and we transmit this signal to our dataset of thousands of samples using AI and we compare the signal to see if it matches. This process is like a fingerprint detection in a police database. If it matches, it sends back the signal and triggers an alert. So the short answer to your first question is we only need one target pathogen to trigger an alert.
Your second question is that we are looking for a pathogen in wastewater from a pipe that serves single premises, a number of cabins on decks of cruise ships, so we will be able to notify the ship captain that there is an infectious disease on the ship and individual testing should be done on a particular deck, or section of the ship before it spreads. The ship can just as easily be a council district, hospital, nursing home, airports. There are other opportunities for testing, but we want to focus on being the Gold Standard for pathogen identification, just as MWG's Microtox Brand is the Gold Standard for water contamination detection.
Good Morning All,
First time post on this board.
I'm looking at this share with interest, and am currently building an investment case.
I do have 2 areas that I'm researching, and would appreciate your help
1) How sensitive would this technology be ?
I understand that reporting would be real time, however i presume that there's a threshold before detection takes place,
In other words : Is there an estimate of how many people would need to have symptoms of a particular virus, before detection is possible ?
2) Perhaps a more basic question ; if detection of a particular virus takes place, then is there an estimate of how many potential carriers are there ? Or in other words, - How localised would this be
No agenda here, - Just 2 genuine enquiries
Thanks for reading :
Oatcake
