Microfluidic Arrays - Now LEGOs Can Do Anything!

Little LEGO pieces shaped like pegs can re-create microscopic activity taking place inside lab-on-a-chip devices, also known as microfluidic arrays, at a scale scientists can more easily observe. Microfluidic arrays are commonly used to sort tiny samples by size, shape or composition, but the minuscule forces work at such a small magnitude, they are difficult to measure. To solve this small problem, the Johns Hopkins engineers decided to think big.  Like LEGO big. read more
