Microfluidic chemistry is a mainstream thing. It's used for all kinds of processes, even in large-scale drug manufacturing to replace batch processes.
I believe this needs to be tested by other parties, results checked, etc. Like science.
Because claims like this ("diagnose," "small drops," "quick") were made before, people ended up in jail for the tactics used trying to protect the lies when they couldn't make it work.
But siezing on the word "microfluidics" because theranos used it, makes about as much sense as seizing on the word "chemistry" and saying theranos also claimed to use chemistry.
What they did, they found a material that allows them to microfluidize the processes.
Can you provide a link to more information about this? I was under the (probably mistaken) assumption that microfluidics were using semiconductor-based lithography processes, and we've figured out how to scale the heck out of that.
I did find an interview with Derek Lowe where they talk a bit on the topic, it I haven’t listened through all of it to see if they discuss microfluidics: https://www.earwolf.com/episode/where-oh-where-is-the-covid-...
EDIT: found it! Here’s the write up where Derek Lowe discusses microfluidics devices that ended up being the bottleneck to producing the original COVID vaccines: https://www.science.org/content/blog-post/myths-vaccine-manu...
From the article (there’s more than this):
Ah, but now we get back to Step Four. As Neubert says, "Welcome to the bottleneck!" Turning a mixture of mRNA and a set of lipids into a well-defined mix of solid nanoparticles with consistent mRNA encapsulation, well, that's the hard part. Moderna appears to be doing this step in-house, although details are scarce, and Pfizer/BioNTech seems to be doing this in Kalamazoo, MI and probably in Europe as well. Everyone is almost certainly having to use some sort of specially-built microfluidics device to get this to happen - I would be extremely surprised to find that it would be feasible without such technology. Microfluidics (a hot area of research for some years now) involves liquid flow through very small channels, allowing for precise mixing and timing on a very small scale. Liquids behave quite differently on that scale than they do when you pour them out of drums or pump them into reactors (which is what we're used to in more traditional drug manufacturing). That's the whole idea. My own guess as to what such a Vaccine Machine involves is a large number of very small reaction chambers, running in parallel, that have equally small and very precisely controlled flows of the mRNA and the various lipid components heading into them. You will have to control the flow rates, the concentrations, the temperature, and who knows what else, and you can be sure that the channel sizes and the size and shape of the mixing chambers are critical as well.
