Problems solved by technology
An important process in the extraction process of the magnetic bead method is magnetic separation. At present, the magnetic separation in the laboratory is generally realized manually using permanent magnets, and the operation process is inconvenient.
At present, the nucleic acid extraction kits produced on the market need to cooperate with complex control and operation instruments to achieve nucleic acid extraction, and the price of such operation instruments is very expensive

The invention relates to an electromagnetic biological sample processing device. The device is characterized by comprising a closed and transparent box body (10), a plurality of reagent reservoirs are arranged at the bottom of the box body; a movable sliding block (12) is arranged above the reagent reservoirs; metal sliding bars (27) are respectively arranged at both sides of the movable sliding block (12), one end of a terminal of the metal sliding bar is arranged on a guide rail (22), the guide rail (22) is respectively arranged at each of both sides of the inner wall of the box body and the other end of the terminal of the metal sliding bar is connected with an energizing coil (16) on an electromagnet (15) located inside the movable sliding block (12); and when the movable sliding block (12) horizontally moves, the terminal of the metal sliding bar is guided by the elastic force of a spring inside the movable sliding block (12) and the shape of the wave-shaped guide rail (22). In combination with a simple external drive device, the processing process of a nucleic acid sample can be carried out in the closed box body and is safe and pollution-free.
Description
technical field [0001] The invention relates to an electromagnetic biological sample processing device, which belongs to the fields of biological science and nanometer material science. Background technique [0002] Nucleic acid research is an important topic in modern biology and medical research. As the carrier of genetic information, nucleic acid is the material basis of gene expression. In addition to playing a very important role in the normal growth, development, and reproduction of organisms, it is also related to abnormal conditions of life, such as tumor occurrence, radiation, etc. Injuries, genetic diseases, etc. are also closely related. Therefore, nucleic acid is an important topic in modern biology and medical research. Whether it is research on the structure and function of nucleic acids, or research on genetic engineering, protein engineering, etc., it is first necessary to separate and purify nucleic acids. Traditional nucleic acid separation techniques in...
