Biochip
Biochip technology
Biochip refers to the orderly solidification of a large number of biological macromolecules on the surface of the support according to the methods of Hiroshima in-situ synthesis or micro-spotting, forming a dense two-dimensional molecular arrangement, and then combining them with the target in the labeled biological sample. In molecular hybridization, the intensity of the hybridization signal can be detected and analyzed quickly, in parallel, and efficiently through a specific instrument, so as to determine the number of target molecules in the sample.
Biochip technology is a satellite biochemical analysis system that integrates the discontinuous analysis process in the field of life sciences on the surface of precious chips or glass chips through microfilming technology based on the principle of specific interactions between molecules, so as to realize the analysis of cells and proteins. , Genetic testing, etc. The target molecules in the labeled biological sample to be tested are hybridized, and the intensity of the hybridization signal is detected and analyzed quickly parallel, and efficiently by a specific instrument, so as to determine the number of target molecules in the sample.
Biochip classification:
According to the different fixed probes on the chip, biochips are divided into gene chips, protein chips, cell chips, and tissue chips.
According to the principle, it is divided into element-type array chips.
Gene chip is currently the most widely used form of biochip
Protein chip common terms disease, immune and biochemical detection
Tissue chip has become the "dark horse" of biochips, and its application areas continue to expand
Micro-nano biochips are effective in treating epilepsy
The above are articles about biochips and biochip technology, I hope they will be helpful to users.
