Micro gene amplification device for miniature space experiment

Abstract

The invention discloses a micro gene amplification device for a miniature space experiment and belongs to the technical field of spatial biological tests. The device comprises a bearing mechanism, a circuit system, a power supply, two groups of amplified biological chips, an indicating lamp and a power switch, wherein a biological sample to be amplified is filled into the amplified biological chips through a filling hole, the circuit system, the power supply and the two groups of amplified biological chips are assembled and encapsulated inside the bearing mechanism through ultraviolet encapsulation, and the power switch on the bearing mechanism controls execution of an amplification task; and meanwhile, an external universal computer or special equipment can be connected with the circuit system through an RS232 interface according to the needs of the flight mission, and the task parameters are set through software of an upper computer. The gene amplification test can be independently finished in a space environment and a ground environment, and the device is small in volume and low in power consumption and can autonomously control the experimental process, display the operating state and bear non-board severe conditions.

Description

technical field [0001] The invention relates to a miniature gene amplification device for space experiments, which belongs to the technical field of space biological experiments. Background technique [0002] Gene polymerase chain reaction (Polymerase Chain Reaction, PCR) technology has rapidly developed into one of the most important new technologies in the field of biological science research and gene diagnosis since it was invented in the early 1980s. With the development of the field of space biology, there is an urgent need to study the missense mutations in the polymerase chain reaction of genes in the space environment (radiation and microgravity) through a new type of amplification device used in space carrying experiments. Provide an important theoretical basis to clarify the possible impact of the space environment on the reproduction and development of organisms and the health of astronauts.

AI Technical Summary

Problems solved by technology

[0003] At present, the gene amplification instrument widely used in the laboratory mainly adopts the semiconductor temperature control system commonly used in the world, which is expensive and difficult to implement.

Moreover, the above-mentioned gene amplification instrument has a large volume and high power consumption, and is suitable for the amplification of large-dose samples, but it is difficult to apply to the amplification of trace samples.
