A study team from Oman has developed a portable device for tripping over insecticides in environmental and food samples. of Higher Education, Research and Innovation. Work awarded in the box of Cultural, Social and Fundamental Sciences in the category of Young Researcher.
For this project of studies, Iman and his team developed a wearable device to verify insecticides on site in environmental and food samples by constructing a chemiluminescence (CL) formula that resulted in emission spikes for selective determination of deltamethrin (MD). This formula is based on the stimulating effect of polyphosphate (PP) on the CL reaction of graphene quantum dots (GQD) – potassium permanganate (KMnO4).
She said the beauty of these paintings lies in offering a formula capable of emitting light from emitting species at other wavelengths under the same experimental conditions. Here, a paper cutting production strategy was used to create the undeniable square-shaped laboratory on a paper device. Several experimental parameters were extensively optimized, adding paper size, order of injection of analytes and CL reagents, and concentration and volumes of reagents.
The requirement of the Ministry of Agriculture, Fisheries and Water Resources to attach a certificate indicating the maximum allowable percentage of pesticide content in local and imported foods increases the burden on importers due to the maximum charge and time required to perform the analysis.
He added that the need for farmers to ship their products over long distances to specialized laboratories can lead to food spoilage in many cases, reducing their profits. a heavy burden on the government, which means spending a lot of cash to supply the tools and specialized technicians, which increases the cost of the investigation and the time required to perform the test.
This research task was performed by Iman al Yahyai, Dr. Haider al Lawati and Dr. Javad Hassanzadeh. It was published in the journal Sensors and Actuators B: Chemical with an impact of 7460.
Iman said: “It is an absolute honour to obtain the National Research Award established through the Ministry of Higher Education, Research and Innovation. This award is very important to me and is a step in my life that inspires me to try harder and I hope to remain as productive as possible in the future. I am incredibly grateful to my supervisor, Dr. Haider al Lawati, for motivating me to continue to have the highest point of determination to achieve these paintings in this way.
