A team of Australian scientists has found an unusual solution to a dangerous problem. The researchers are acclimatizing a component from innovative solar cells to create a quick, light-based detection system for some of the fatal toxins. On the international platform, the use of chemical warfare agents including mustard gas (sulfur mustard) is strictly banned. However, the demand for chemicals for industry, agriculture, and other daily lives such as methyl iodide is found to increase. If the fumigants were used in uncalculated quantities and for incorrect application, it could prove harmful to the toxic to humans and also will degrade the ozone layer.

As themethyl iodide is invisible and odorless, its dangerous amounts remain unpredictable. Until now, the researchers tested it in the laboratory through expensive andintricate equipment, which in reality is difficult to set up.The cost-effective detection methods were found to be less sensitive with longer delivery time for results. The ARC Centre of Excellence researchers found color changes to help detect methyl iodide with great accuracy, speed, and flexibility. The latest method is flexible enough to be useful for detecting other fumigants and chemical warfare agents.

The collaboration with Australia's national science agency CSIRO and the Department of Defence has helped the researchers gain access to some new technology such synthetic nanocrystals used toadvance solar power and they turned it into a detection method. The researchers stated that the highly fluorescent nanocrystals reacted with the fumigants causing a switch in the color of the light being emitted. In the presence of fumigant, the nanocrystal emission shifts to green, yellow, orange, red, and finally deep red. The perovskite nanocrystals are known to efficiently emit light and this has encouraged the team to study the reaction between methyl iodide and perovskites through a simplechemical activation step.The use of perovskite nanocrystals technology can help protect our military and first responders by detecting different types of methyl halide species, pesticides, and chemical warfare agents, such as teargas and mustard gas.
