Cutting boards can produce #microparticles when used to chop veggies, study shows >@EnvSciTech https://pubs.acs.org/doi/10.1021/acs.est.3c00924 https://phys.org/news/2023-06-boards-microparticles-veggies.html

Do you know those annoying layer lines on #3Dprinted parts? In resin #3Dprinters, they are as small as 25 microns… And we can make #microfluidics molds with these printers. Does this mean we can reach 25 microns features in Z?

YES! We can make a mold for a “staircase” microfluidic device. Now we have steps of 25um on the height of the channel. This #microfluidic does not only filter #microparticles, but also size-sort them. Particles of different sizes will be blocked on different steps.

Can you use standard #3Dprinters to make #microfluidics for separating #microparticles down to 25 micrometers? Spoiler alert: YES we can on a “staircase microfluidic device”
But why and how? Paper here: https://chemrxiv.org/engage/chemrxiv/article-details/63fb0342937392db3d1126e6 1/12

#Microparticles, from tens to hundreds of micrometers, are everywhere: parasite eggs in urine, #microplastics in water, #plankton, etc. You need to filter or centrifuge quite some litres of liquids to detect them. Not nice if you are in the field. 2/12
