At the end, we compared all the different methods (also with computational methods). You can find all the results here:

We tried different fabrication methods, from 3D printing, laser cutting, and even a benchtop CNC. All of this with a simple off-the-bench transducer :) 2/3
With our second preprint in a week, we've entered the world of acoustofluidics with our standard question:
"How can we make high-precision acoustofluidic chips more accessible and cost-effective?" 1/3 chemrxiv.org/doi/full/10....
Halbach arrays are always so photogenic :)

just saying.....
Apparently, today is World Plumbing Day.....
but what about microplumbing day???

Do you have any idea if it is possible to do microscopy using Schlieren optics?
Such creative work!
Very cool work. When life gives you layer-line lemons, make microfluidic lemonade!
Thanks :)
Very straight in the mm to cm range, then it depends on the printer I would say.
Did you know the amazingly awesome Open Hardware Summit is coming up in Berlin? May 23-24!?
We will even do a workshop making Mothboxes there!

Does that work?
Oh yes, and we can have beautiful 15um parallel channels, which can be done at home with a simple FDM printer. Those chips will be exploited for surface sensing (high surface area + low height). 5/5
preprint here: chemrxiv.org/doi/full/10....
But then we don't want to use plasma to attach the PDMS to the glass, so we 3D-printed a couple of clamps to make the PDMS-Glass attachment. 4/5
What if we can replicate the layer lines of the FDM printers in PDMS? Those ridges should be quite small, right? right?
Indeed, they are; they can be as small as 15 µm, as seen in the SEM images of the plastic and the PDMS replica. 3/5
Microfluidics with high surface area and small height are vital for surface sensors, as the analyte must diffuse to the bottom of the channel. Fabricating those chips is difficult, expensive, or both. FDM 3D printers do not have the resolution for making those sub-20um channels.
Or do they?
2/5
Do you know those annoying layer lines you get with FDM 3D printers? Those layers you try to avoid or hide?
What if I tell you we can use them to make 15-micrometer-tall microfluidic channels?

I had a very weird reviewer comments on our last review paper. They asked for more data for one experiment… but it’s a review paper, we didn’t do any new experimental work….
Hi All.
Here is Alex Pinto, chemistry professor at Manhattan University, in NYC. I use to have a twitter with a couple of followers. Now, I am finally at BlueSKy. If you used to follow my group on Twitter, please, follow us here on BlueSky. I hope to keep the same vibe we used to have on Twitter.
let's fire up the 3D printers :D
