I’ve spent 1-2 years designing everything, even bought many parts to start building and written some code. But I realize that a project like this can’t be successful without a community.
I’ll be brief here: such a device would help bring many of the coming medical advances to the masses, even to people that can’t afford them, as well as make research cheaper for non-corporate-backed groups.
If you think this is important, I could share what’s been done and we could discuss ideas, get organized, find people with skills that would like to help, etc.
Are there 3D printers that can print such fluid circuits in sufficient quality?
I would start with a more practical use-case. What would be the immediate use of separating commercial enzyme mixtures?
I’ve bought a good 3D printer and experimented with it. Right now I’m pretty sure it can be done, although not at a terribly high resolution.
Okay, enzyme separation huh… I can imagine separating pure enzymes from something like a cheap non-laboratory mixture (e.g. digestive enzymes) or a used up reaction mixture.
Yeah, print resolution is what I was wondering about since the capillary forces need a certain size to work.
Maybe it would be easier to start with enzyme detection? For environmental monitoring purposes etc.?
Oh, no, it won’t use capillary forces in the current design. Rather, it will actively pump fluids through the channels, so they only need to be thin enough to allow laminar flow and force any bubbles through.
Environmental enzyme detection, huh? I like that use case, seems relatively simple yet useful to start with!
