@13thMonkey It is interesting you mentioned Theranos. As an engineer, I was fascinated by the concept behind the objective of what Elizabeth Holmes sought to achieve in her Theranos project. If you watched the HBO documentary "Out for Blood in Silicon Valley" you see where there was so many moving parts inside the diagnostic equipment. Moving chemicals and blood samples, assays and contents of pipettes poses a high risk of cross contamination.
A single drop onto another area could undermine all future testing without the inside being cleaned out after each test. Most technology pioneers who set out to create something new, fail, or at best, are held back because they are creating as they go along.
But success is best built on the failures, or failings and mistakes of those gone before. Windows, and Apple user display on their computers. Nokia, Apple, Samsung and Huawei on smart phones.
Integumen's Rinocloud AI system for detecting e.coli in 4 seconds was built on top of collections of sampled water, brought to be laboratory and processed by lab technicians growing bacteria over 24 to 72 hours to confirm that the water source is contaminated.
Modern Water's Microtox equipment use bio luminescent reagents, which lose their brightness if contaminated with a range of virus, toxins and other bacteria to trigger an alarm, confirming the water source is contaminated.
Adding those two elements together is logical. Both work and have done over a number of years.
Looking for a specific target in contaminated water (like SARS-CoV-2) is better if you have a proven virus capturing agent (Affimers from Avacta and Aptamers from the Aptamer Group)
Pulling all three proven technologies together builds on the success, out of failed experiments over years, to get it right.
Theranos sought the Holy Grail, without a map or milestones. Whether it is liquid from water, blood or milk (mastitis), once you have the pieces that already work, then the outcomes becomes more certain.
One final lessons on Theranos. Don't use moving parts that carry liquids, as the risk of drips and spills and cross-contamination lead to one failing that should be overcome with any future solution. We know that lesson is costly, and eliminated it before it became an issue.
