In molecular biology, biochips are essentially miniaturized laboratories that can perform hundreds or thousands of simultaneous biochemical reactions. Biochips enable researchers to quickly screen large numbers of biological analytes for a variety of purposes, from disease diagnosis to detection of bioterrorism agents. Like a computer chip that can perform millions of mathematical operations in one second, a biochip can perform thousands of biological reactions, such as decoding genes, in a few seconds. ... A specially designed microscope can determine where the sample hybridized with DNA strands in the biochip Thousands of people in Sweden are having futuristic microchips implanted into their skin to carry out everyday activities and replace credit cards and cash.
