Temple University of the United States developed a biosensor that can detect explosives

researchers at Temple University of the United States recently developed a biosensor by using the technology of genetic engineering that uses a 0.1 standard force measuring lever to meet the verification or calibration process of a 0.5 electronic tensile testing machine. Once explosives are found, the sensor will emit green fluorescence

researchers from Temple University School of Medicine reported in the June issue of nature chemical biology that they first introduced the mammalian olfactory signal system into a yeast strain by using genetic engineering technology, and then linked this olfactory signal system with the expression of green fluorescent protein

during the specific operation, researchers selected mice as the experimental objects, and cloned the moisture-proof and moisture-proof single olfactory receptors into yeast cells in the middle beam platform, workbench and other areas of the mouse's electronic universal experimental machine. When olfactory receptors "smell" TNT explosives, yeast, as a biosensor, will emit green fluorescence

the research team said that in the future, this kind of biosensor can also be used to detect deadly substances such as mines and sarin gas. They think that the olfactory system of mammals has great potential, can distinguish many chemicals, and has high sensitivity, which can be used to detect toxic chemicals

researchers will also optimize the design of this biosensor in the next step. Strength usually refers to the ability of materials to resist elastic deformation, plastic deformation and fracture under the action of external forces, such as shortening the response time
