A biochip is a tiny device used to analyse the organic substances found in living things. A Biochips are a tiny laboratory that has the capacity to carry out hundreds of biological activities simultaneously. It is a group of micro-test sites or microarrays arranged on the surface of a solid substrate and is made to run a number of tests concurrently in order to increase throughput and speed. Similar to a computer chip, a biochip performs biological functions like gene decoding and contaminant detection in a couple of seconds rather than hundreds of mathematical calculations per second.
