McGill University researchers have made a breakthrough in diagnostic technology, inventing a ‘lab on a chip’ that can be 3D-printed in just 30 minutes. The chip has the potential to make on-the-spot testing widely accessible.
As part of a recent study, the results of which were published in the journal Advanced Materials, the McGill team developed capillaric chips that act as miniature laboratories.
Unlike other computer microprocessors, these chips are single-use and require no external power source — a simple paper strip suffices.
They function through capillary action — the very phenomena by which a spilled liquid on the kitchen table spontaneously wicks into the paper towel used to wipe it up.
“Traditional diagnostics require peripherals, while ours can circumvent them...
