Perovskite Quantum Dots Supplier - Alfa Chemistry

Quantum Dot Fluorescent Probe for pH Measurement Services


Quantum Dot Fluorescent Probe for pH Measurement Services

Alfa Chemistry has been working hard to bring a wide range of services to customers around the world. We have top technical professionals who constantly update quantum dot products and corresponding quantum dot services. In order to provide better services, our research methods and vision are more far-reaching, the purpose is to bring the most advanced technology products and corresponding services to customers.


The surface structure of quantum dots has a strong sensitivity to pH, so people often use its response to pH to study the changes in pH of biological systems. Quantum dots are made into fluorescent probes that can be used to detect the pH value of the virus and the pH value in the water phase. The quantum dots usually used as pH response are concentrated in Cd quantum dots, but because of their certain toxicity to biological systems, and the steady-state fluorescence spectroscopy is unstable due to the influence of factors such as concentration, non-toxic quantum dots are used ZnSe quantum dots, such as ZnSe quantum dots, have low biological toxicity and good biocompatibility, and are suitable for use in biological systems. In detection, the quantum dot pH value fluorescent probe has the highest sensitivity in the pH range of 6-8, and this pH range is very suitable for living organisms. The quenching of the quantum dot fluorescence probe by the colleague's metal ions is a static quenching, which will not affect its fluorescence lifetime.
