Perovskite Quantum Dots Supplier - Alfa Chemistry

Custom Quantum Dot Fluorescence Detection of Acephate


Custom Quantum Dot Fluorescence Detection of Acephate

Quantum dots are characterized by high fluorescence quantum yield, wide excitation spectrum, narrow emission spectrum, strong photobleaching resistance, good optical stability and easy modification, and have been widely used in biological imaging analysis, detection of heavy metal ions, biomarkers, drug determination, DNA and protein detection. Alfa Chemistry is at the forefront of scientific research and provides customized quantum dot detection services to our customers.


Acephate is also known as homophos and its chemical name is O, S-dimethyl-N-acetylthiophosphoramide. It is a systemic insecticide, which mainly inhibits the acetylcholinesterase in insects. It has stomach toxicity and contact killing effect, and has a certain fumigation effect. It is a slow-acting insecticide. The insecticide is mainly used to control pests on crops such as vegetables, fruit trees, rice, cotton and wheat. In actual fruit and vegetable cultivation, excessive and irregular use of acephate will easily make it remain in fruits and vegetables, which will endanger human health. At present, the detection methods of acephate mainly include gas chromatography (GC), high performance liquid chromatography (HPLC), and liquid chromatography-tandem mass spectrometry (LC-MS/MS). However, these methods have shortcomings such as susceptibility to matrix interference, cumbersome analysis process, lengthy time, and expensive equipment.


Quantum dot service platform is committed to providing customers with very comprehensive and extensive services, our professional team including master, doctor and other high-end technical personnel, can specifically customize the quantum dot services you need. Our services include the following:

  • Custom CdSe/ZnS Quantum Dots
  • Acephate Test

Fluorescence Response Mechanism

With the increase of acephate concentration, the fluorescence intensity of CdSe/ZnS QDs occurs regular quenching phenomenon. In general, the fluorescence intensity of CdSe/ZnS QDs will be quenched by energy transfer and quantum dot surface effect. The interaction between acephate and CdSe/ZnS QDs increases the occurrence of surface defects and non-radiative recombination of CdSe/ZnS QDs, resulting in dynamic fluorescence quenching of CdSe/ZnS QDs.
