HTTP:: Music Drives Samples Through New Lab on a Chip
--------
A microfluidic device, or a lab-on-a-chip, is a contraption that is able to detect certain chemicals or microorganisms in minute samples of materials that are passed through it. Experimental samples can be made to pass through it via electromechanical valves, which is the preferred method among scientists. However, experts at the University of Michigan have recently demonstrated that music can also be used for the same purpose, replacing the existing valves. Details of the find appear in the journal Proceedings of the National Academy of Sciences (PNAS), in the issue that appeared in the week of July 20th.When the technology of microfluidic devices will develop sufficiently enough, they will become an everyday commodity. Because they combine numerous functions into a single machinery, they could be used to determine if there are any contaminants in tap water or in grocery food, or if the air conditioning is functioning properly. Their limited sizes, of a few millimeters to !
a few centimeters, will replace bulky laboratory equipment, and will allow home owners to bring science into their kitchens.At this point, labs-on-a-chip are used in connection to a computer, which coordinates a vast network of air hoses, valves and electrical connections between the tw...
