    Did marine life in the palaeocene use a #compass?
    Based on a sophisticated method, an international team has succeeded in mapping #magnetic domains in giant fossilised magnetic #microparticles: these may have served as compasses for ancient organisms

  6. 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.

  7. 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: chemrxiv.org/engage/chemrxiv/a 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
