Rapid Detection Service for Dichlorvos


Rapid Detection Service for Dichlorvos

Alfa Chemistry's customized pesticide rapid detection service includes the development of quantum dot designs for pesticide detection to detect laboratory report data. As a leading service provider in the field of quantum dot drug detection and research, we have accumulated rich experience, including the detection of components in plants, organophosphorus and other services.


Excessive use of organophosphorus pesticides can cause pollution and threaten people's health and safety. Currently, the commonly used detection methods are chromatography and spectroscopy. In this case, large instruments are required and time-consuming. The enzyme inhibition method1 has the characteristics of low detection limit and convenience, by preparing an enzyme street biosensor to detect organophosphorus reagents. This method is based on the method based on the inhibitory effect of malathion or trichlorfon on the enzyme, which prevents the production of thiocholine during the immobilization process, thereby increasing the amount of AgNPs. The efficiency of the enzyme activity was measured during the process of adding organophosphorus pesticides (OPs), and the increase of AgNPs depends on the concentration of OPs, and it can be used to treat malathion and trichlorfon at 420 nm by ultraviolet-visible spectroscopy. For detection, the detection limits are as low as 0.455 nmol/L and 5.46 nmol/L. In addition, this detection method has also been successfully applied to the detection of OPs in actual samples.


The technical experts of Alfa Chemistry provide a full set of customized services from carbon quantum dot products, quantum dots for drug analysis and biological small molecule detection. For details, please consult our customer service staff.

According to customer needs, Alfa Chemistry can provide you with:

  • Organophosphorus Detection
  • Result Analysis and Project Report


In order to achieve rapid and accurate detection of dichlorvos in food, carbon quantum dots (CDs) doped with non-metallic elements (nitrogen, sulfur, silicon) were prepared by hydrothermal carbonization, using dynamic light scattering, X-ray diffraction, and X-ray photoelectron energy. Spectroscopy and other means to carry out structural characterization and element analysis. Further based on the principle of enzyme inhibition reaction, a CDs/M2+/acetylcholinesterase reaction detection system was constructed, and the prepared fluorescence sensor was applied to the detection of organophosphorus pesticides. Since carbon quantum dots have a graphene structure, have good water solubility and photoluminescence, nitrogen, sulfur, and silicon are present on the surface, and contain functional functional groups mainly containing oxygen and nitrogen, the prepared fluorescence sensor Used in the detection of organophosphorus pesticides (dichlorvos).
