Biochips refer to the complete fundamental functional unit, capable of performing multi biochemical tasks simultaneously. Tissue chips on the other hand are similar miniaturized units that can replace a tissue or some part of it, enabling the organ to work normally. Both biochips & tissue chips have been elemental in tissue engineering technology and have proven to be of utmost importance in the same arena. DNA microarray also called as biochip in simple terms consists of a two dimensional grid system where upon sensors or solid flat substrates are incorporated. These solid substrates can be either positively charged just like silicon or glass or can also be consisting of integrated circuitry units that perform best in signal transduction studies. The availability of genetic sequence information in both public and corporate databases has gradually shifted genome-based R&D away from pure sequencing for sequencing's sake and toward gene functionâoriented studies. It soon became apparent to everyone involved in genomics that gene sequence data alone was of relatively little clinical use unless it was directly linked to disease relevance. This, in turn, has driven the development of the field of pharmacogenomicsâan approach that seeks to develop drugs tailored to individual genetic variation.
