生物芯片（Biochip）.docVIP

生物芯片（Biochip） Biochip technology originated from nucleic acid hybridization. The so-called biochip generally refers to high density in fixed support each other on the medium molecular biological information (e.g., CDNA gene fragments or peptides and proteins) of the microarray chip (micro-arrays), sequence and position of each molecule in the array are known, and the lattice is a sequence of predetermined. Microfluidic chips (microfluidic, chips) and liquid biochips are new technologies for biochip development than microarray chips, and biochip technology is the basic content of system biotechnology. What is a biochip? In brief, a biochip is a biological sample that is placed on a piece of glass, silicon wafers, nylon membranes, etc., and then it collects signals from an instrument and analyzes the data with a computer. Like the same cloth colorful biological chip one might easily connect, bio chip and electronic chip while the bio chip and electronic chip is inextricably linked, but they are two different things. The biological chip is not equal to the electronic chip, just borrowed the concept, its name was DNA microarray, because it is what happens in the cross reaction of columns. The concept of chip comes from the concept of integration, for example, an electronic chip means to integrate large things into small ones and integrate them together. Biochip is also an integration, but it is an integration of biological materials. Like laboratory tests, examining blood glucose, protein, enzyme activity on a biochip is based on the same biological reaction principle. So biochip is a carrier platform. There are many kinds of materials on this platform, such as silicon, glass, film (cellulose membrane), and some three-dimensional structure of the polymer, the platform is densely packed with various biological materials. The chip is just a carrier. Do what, test what, or rely on biologists to complete. That is to say, a large number of test tubes are needed in a large la
