Disclosed is a magnetic liquid experimental chip for biological determination, and is suitable for conducting determination analysis on rare biological samples. A laboratory comprises a first injection pump (1), a second injection pump (2), a first syringe (3-1), a second syringe (3-2), a third syringe (4-1), a fourth syringe (4-2), magnetic liquid (5), a capillary tube (6), a reaction chip (7), an excitation coil matrix (8) and a waste liquid collector (9). All independent coils are controlled to be powered on or powered off, so that a magnetic field can be generated in the reaction chip (7), the magnetic field can control the movement trajectory of liquid droplets formed by the magnetic liquid (5) in the reaction chip (7), and therefore the movement trajectory of the liquid droplets is changed through the collision of the liquid droplets formed by the magnetic liquid (5), droplets of a tested solution and droplets of a biological sample solution to be tested, the droplets of a tested solution and the droplets of a biological sample solution to be tested meet and react on the reaction chip (7), and signals are output through the reaction chip (7).
Description
technical field [0001] The invention belongs to the field of biological testing and is suitable for measuring and analyzing rare biological samples. Background technique [0002] At present, with the development of biological testing technology, higher requirements are put forward for the precision, speed and accuracy of testing. Traditional biological tests often titrate the powder of biological samples or the solution prepared by dissolving them with related solutions in a test tube to produce a chemical reaction, and then determine the composition of the biological samples. [0003] However, many biological samples are extremely rare, and the macroscopic titration method consumes too much biological samples, so it is not allowed to use this method for measurement and analysis, thus the concept of the experimental chip was proposed. Domestic research on experimental chips is still in its infancy, such as the patent "Lab on a Chip for Alkalinity Analysis" (patent applicati...
