Good biocompatibility: Sulfur quantum dots are widely used in cell imaging and biomedical research due to their low toxicity, no heavy metal pollution, and good biocompatibility.

Application of Sulfur quantum dots liquid


Fluorescent probe detection: Sulfur quantum dots, as fluorescent probes, can detect heavy metal ions such as PB (II) and BI (III) with low detection limits and good sensitivity.

Cell imaging: In the biomedical field, sulfur quantum dots are used for cell labeling and imaging. Due to their high fluorescence intensity and good biocompatibility, they can clearly observe the internal structure and dynamic processes of cells.

Optoelectronic conversion: The application of sulfur quantum dots in optoelectronic conversion devices has also received widespread attention, and their excellent optical properties make them ideal materials for optoelectronic devices.

Chemical catalysis: Sulfur quantum dots exhibit excellent performance in chemical catalytic reactions, and their unique optical properties and high stability make them of great value in catalyst design and optimization.

Environmental sensing: Sulfur quantum dots have also been widely used in environmental monitoring and pollutant detection, and their high sensitivity and specificity make them ideal sensing materials.


instructions

Caution: Sulfur quantum dots should not be mixed with acidic media. If dilution is required, it is best to dialyze before dilution. Dialysis should use low concentration alkali to remove high concentration alkali and other ions, and then dilute again. If there are no dialysis conditions, alkaline solvents can be directly used for dilution. It is recommended to dilute with 0.1M NaOH or KOH solution.

The particles of sulfur quantum dots have aggregates of large particles (20 to 80 nm), which are composed of small nanoparticles smaller than 5 nm.
