Perovskite Quantum Dots Supplier - Alfa Chemistry

Custom Graphene/CdTe Quantum Dots Complexes Services


Custom Graphene/CdTe Quantum Dots Complexes Services

The quantum dots are coated with silica, and malachite green is added in the process of forming the silica surface layer to obtain silica-coated CdTe quantum dot microspheres with malachite green loaded on the surface. The malachite green on the surface of the ball is eluted to obtain molecularly imprinted microspheres, which can be quantitatively analyzed for malachite green. Alfa Chemistry has been continuously developing new business areas of quantum dots for a long time and broadening the applications of quantum dots. Our professional team can develop a very complete quantum dot solution for you.


Malachite green, as a toxic triphenylmethane compound, gets its name because its color is very close to malachite. Long-term consumption can cause cancer. There are many analytical methods for malachite green, such as electrochemical molecular imprinting, high performance liquid chromatography, immunoassay, colorimetry, molecular imprinting, and fluorescence. As a type of fluorescent nanomaterials, quantum dots have good fluorescence emission performance. Many analytes, including food additives, drugs, human metabolites, etc., will react with them, causing significant changes in the fluorescence intensity of quantum dots. Among them, the graphene/CdTe quantum dot composite is based on the strong fluorescence quenching effect of bright blue on the graphene/CdTe quantum dot composite.
