Abstract: (2347 Views)
Background: Endosulfan is an organochlorine insecticide and acaricide that is being phased out globally. There are significant environmental concerns of endosulfan due to its persistence and toxicity. Their alternatives include newer, less persistent, and more toxic insecticides, as well as the integrated weed management practices that are used.
Materials and Methods: In this study, with a facile method, CdTe QDs coated with ioglycolic acid (TGA) were synthesized through hydrothermal methods. And they were used as new fluorescent nanosensors for chlorine poison in biological samples. This sensor can also be used for endosulfan drug detection with excellent sample resolution, wide linear range, and low detection. Therefore, this method is a relatively practical and economical method.
Results: This type of CdTe QDs fluorescent Nano sensor is acceptable for the determination of endosulfan at the micromolar level. According to the XRD results, there was no change in the crystal structure of CdTe QDs. The fluorescence intensity increases or decreases by changing the volume of buffer and CdTe QD, pH, ionic strength and time.
Conclusion: A simple type of IFE method was studied in comparison with complex and expensive processes in the determination of endosulfan, which can be recognized as a simple, specific and immediate alternative method to solve the real problem.
