Apparently, in the production of mRNA vaccines the microfluidic components play a major part in encapsulating the mRNA in a stable lipid coat (the technical term is likely not 'coat'). This step is also apparently a bottleneck in vaccine production (FWIW I still think patents should be waved to ease global vaccine production, though other things are needed as well). I wanted to ask how microfluidic devices used here are built, but with a short google I didnt even find out how one looks like - So I ask about that:
How does the device look like? How is the basic function? How large or small is the mixer in a n industrial application? I've seen picutres where reaction chambers, mostly stainless steel blocks with the chamber milled inside, where assembled lego-like on a board and fitted together with a vise or similar - this appears to be appropriate for lab work, but maybe the same systems are used for production?
So, I hope that someone here has either better google foo than me or works in the industry and can share some knowledge - there's a huge area between trade secrets and the trivially googleable, usually hidden in trade press and catalogs, that is available to someone with experience in the relevant industry.
