Infectious Disease Detection
Inquiry
As a professional quantum dot supply platform, Alfa Chemistry has been conducting research on quantum dots in addition to providing quantum dots to expand the application fields of quantum dots. In the detection of infectious diseases, quantum dots also play an important role. Our professional team including bachelor's, master's and Ph.D. can bring you comprehensive and scientific services.
Background
In the diagnosis of infectious diseases, the accurate detection of specific pathogens is an important basis for clinical diagnosis. However, the existing detection methods for infectious diseases, such as microbial culture, immunological detection, molecular diagnosis, etc., have the limitations of long detection cycle, low specificity and low detection rate. The quantum dots provide feasibility for solving the above-mentioned problems. Compared with traditional organic fluorescent dyes, quantum dots have the following physical and chemical properties: the wavelength can be adjusted, and the size or composition ratio of the quantum dots can be controlled to show different colors of fluorescence; it has a narrow and symmetrical emission spectrum, which reduces the spectrum overlap in detection ; High fluorescence efficiency, long life; stable properties, not easy to photobleaching and photolysis, etc., can be widely used in the detection of infectious diseases, tumors, and other including metal ions.
Services
Alfa Chemistry cooperates with medical research institutions to screen out suitable quantum dots for the detection of infectious diseases. And constantly optimize technology, provide customers with the most professional services to meet customer requirements. Our services mainly include:
- Infectious Disease Pathogen Nucleic Acid Detection
- Infectious Disease Protein Detection
Detection technology
- Quantum dot fluorescence polarization technology
Using different quantum dots as markers, simultaneous detection of the GBP6 and TM-CC1 genes of Mycobacterium tuberculosis realizes multiple detections based on quantum dots, opening up a new way for new methods of tuberculosis diagnosis.
- Bi-color graphene quantum dots and carbon nanoparticles biosensing platform
Combined with exonuclease III auxiliary signal amplification, it can detect multiple targets at the same time and the detection limit is as low as 6.6 pmol/L, which proves that quantum dots have the characteristics of high sensitivity and multiple detection, and have great potential for clinical diagnosis.
- Quantum dot biosensor
The nano-biosensor that performs resonance energy transfer between quantum dots and dark quencher-labeled peptide probes is used to detect BoNT/E. This method is simple to operate, with a detection limit as low as 2 ng/mL, and is suitable for non-target BoNT serotypes In the test, the nano-biosensor showed good specificity and sensitivity to the target.
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.
