Description

technical field [0001] The present disclosure relates to the technical field of air microbial collection and detection, and in particular to an automatic sampling and detection device and method for adjacent spaces. Background technique [0002] Near space refers to the airspace 20-100 kilometers above the ground, and its environment is most similar to the environmental conditions of the early Earth and Mars. Therefore, the study of microorganisms in near space has important implications for revealing the origin of human life on Earth and the source of life in the universe. Due to the harsh environment of near space and the lack of corresponding on-orbit detection technology at this stage, there is still a lot of controversy about the biomass existing at different altitudes in near space. [0003] In the existing research technology, the main near-space biomass detection method is to first sample from the stratosphere, and then bring the samples back to the ground for detect...

AI Technical Summary

Problems solved by technology

The method of taking samples from the critical space and then bringing them back to the ground for testing has major limitations. For example, bringing samples from the critical space back to the ground for testing is likely to pollute the samples, and many bacteria cannot be cultured due to environmental changes.

The current detection methods for biomass in samples also have deficiencies, for example, fluorescent staining and culture counting methods cannot detect cell viability, and DNA sequencing technology is complex and can only identify species

Patent 200710179864.4 provides a rapid detection method for the total number of bacteria based on Adenosine Triphosphate (ATP) bioluminescence method, but this method does not contain the content of microbial sampling

[0004] The above methods cannot realize the functions of real-time sampling in the temporary space and detection of biomass in the adjacent space at the same time. Therefore, it is of great significance to develop an on-orbit automatic sampling and detection device in the adjacent space.
