Lego Blocks Simulate Microfluidic Filters 26
BuzzSkyline writes "Researchers at Johns Hopkins University are playing with Lego blocks to discover how arrays of nanoscopic obstacles could sort cells and other tiny particles by size. Ball bearings dropped through an array of Lego pieces submerged in glycerin serve as an analogue of the tiny systems, with bearings of different sizes taking different paths through the array. An academic paper describing the Lego research recently appeared in the journal Physical Review Letters (subscription required)."

Lego? Microfluidic Filters? Yeah and if I reverse the polarity on the main communications array, a tachyon pulse will be generated.

Nonsense, obviously the emergency capacitors would absorb any access energy created by the array. The only side effect was in they overloaded they would discharge through the main reactor core overloading several systems, possibly causing a flux in the hyper-drive which would create a tach...
oh wait you are right.

Biochemists already do this with proteins [wikipedia.org] and other biochemicals and I'm sure other fields have done this with other things. Is this only new and exciting because legos are being used?

This is entirely different. The particles come out of the filter at different places rather than at different times.

I build microfluidic devices and man it can be time consuming to design fabricate and test them. To design a good device you have to draw up the design, fabricate it (often in a clean room) and then assemble and test it. With this I could just get a little slimy and in 30 minutes have a good idea if what I have is going to work...Now I just have to convince my boss I'm not just playing with Legos at work

The researcher answers the question:
* Lego is available and accessible, moreso than developing tools or using ad hoc scavenged parts to make your own pegs
* Lego is machined to fairly high standards of consistency and clean geometry, which helps this particular study

Seems like it would be better to just simulate in on the computer. Legos submerged in glycerin sounds like a terrible mess.

Is there anything they can't do?
