DGIST’s Physics and Chemistry Professor Park Jin-hee and her analysis workforce have developed a know-how that permits simple detection of hazardous chemical substances. Permitting one to detect dangerous substances by analyzing shade modifications utilizing a cell phone digital camera, the know-how is predicted to be utilized for numerous functions, such because the detection of environmental air pollution and prevention of fuel leakage.
“Risky natural compounds” are dangerous chemical substances which are broadly current within the surroundings. They enter the surroundings by way of manufacturing unit gases, indoor air, and different sources and trigger air pollution and generally even diseases. Subsequently, it’s critical to detect them rapidly. Conventional detection strategies are both costly or can detect solely a restricted variety of chemical substances.
To resolve this drawback, Prof. Jin-hee Park and her workforce have developed a sensor that makes use of a cloth referred to as “metal-organic framework” to induce shade modifications. The sensor has been created utilizing six completely different solvents, which may distinguish between 14 unstable natural compounds and water. To allow the remark of shade modifications with the bare eye, the workforce has developed large-area movies that may be simply produced at a low value.
By analyzing shade modifications utilizing a cell phone, it’s doable to detect, qualitatively and quantitatively, low concentrations of dangerous compounds which are troublesome to detect with the human nostril. The sensors could also be used for numerous functions, resembling environmental air pollution detection and fuel leakage prevention, as they carry out nicely even in high-humidity environments.
“The sensors we now have developed have nice industrial potential as a result of they’re operable with out energy and implementable at low prices,” stated Prof. Lee. “With these sensors, we stay up for securing supply applied sciences to develop sensors for numerous functions, resembling environmental air pollution detection, terrorism prevention, and security accident prevention.”
The analysis is revealed within the journal Superior Supplies.
