micro array - Computer Definition
A semiconductor device that is used to detect the DNA makeup of a human cell. DNA chains comprise molecules that pair with each other, and micro arrays contain millions of DNA strands designed to mate with their other half as the liquefied human cells are poured over them. This "hybridization" process is then detectable by a laser. Micro arrays are revolutionizing medicine by being able to pinpoint a very specific disease or the susceptibility to it. Sometimes called "biochips," Affymetrix (www.affymetrix.com) pioneered this technology with its GeneChip family. See Human Genome Project.
