Perovskite Quantum Dots Supplier - Alfa Chemistry

Prediction and Diagnosis of Alzheimer's Disease


Prediction and Diagnosis of Alzheimer Disease

As a professional manufacturer of quantum dots, Alfa Chemistry has been continuously launching new products and expanding new applications. Quantum dots are widely used, among which medical testing is more eye-catching. Medical testing services can screen out specific quantum dots and then use professional technical means to detect infectious diseases, cancer, and Alzheimer's disease.


Amyloid beta (amyloid beta-protein, Aβ) is one of the main pathological marker proteins in the brains of Alzheimer's disease patients. The formation and deposition of Aβ run through the entire pathological process of Alzheimer's disease. Accurate detection is conducive to the early prediction, diagnosis and treatment of Alzheimer's disease. Because the traditional fluorescent dye thioflavin T interferes with the aggregation of Aβ, the use of this dye will make the detection result inaccurate. There is a linear relationship between the fluorescence intensity of graphene quantum dots and Aβ. Graphene quantum dots are used as a new type of probe for detecting amyloid monomers to accurately detect Aβ monomers and Aβ fibrils, which can be further used for degenerative diseases and Detection and diagnosis of other conformational diseases.


The Bachelor, Master, and Ph.D. quantum dot team of Alfa Chemistry has been striving to be at the forefront of quantum dot research, and through cooperation with medical research institutions, it can provide researchers with integrated medical testing services. Among them, Alzheimer's disease testing services include:

  • Test Report
  • Product Solutions

What needs customer attention

  • Choose the right non-toxic quantum dots
  • Most quantum dots contain heavy metal elements, such as cadmium (Cd), which can easily cause kidney, lung and other organs to be poisoned and diseased, and cause pollution to the human environment.

  • The low "flicker" phenomenon and the "light brightening" effect of quantum dots
  • The "flicker" phenomenon refers to the random transition between the emission state and the non-emission state of the quantum dot, which causes its fluorescence to flicker, which affects the detection of a single quantum dot; Continuous excitation, the fluorescence intensity of quantum dots will gradually increase, affecting quantitative detection.
