Abstract:

There are many kinds of small molecule compounds, and play key roles in many biological processes, which has important detection significance and value. The development of its rapid and sensitive visual detection technology is a research hotspot at present. Biosensor based on riboswitch provides a new way for small molecule detection due to its advantages, such as high recognition characteristics, simple operation and low cost. In this paper, the source, composition, regulatory mechanism, in vivo and in vitro screening of riboswitches, especially the classification of riboswitch biosensors based on small molecular targets were introduced, which aimed to provide a theoretical basis for the development and application of small molecule target riboswitch biosensor.

Key words: small molecule target, riboswitch, biosensor, screen, gene expression regulation
