Sulfonate-based Monodisperse polystyrene microspheres

Product Name

Name:a>Sulfonate-based Monodisperse polystyrene microspheres

^{Product Overview}

Monodisperse polystyrene microspheres (Monodisperse Polystyrene Microspheres (PS) is a special polymer microsphere material, usually presented as an emulsion colloid, spherical shape. The particle size distribution is very narrow, that is, all microspheres are very close together, thus forming the monodisperse nature. The particle size of microspheres can be controlled according to the preparation method and conditions, but is often described as "monodisperse", implying a very narrow size distribution. The surface of monodisperse polystyrene microspheres is prone to chemical modification and can introduce different functional groups as needed, thereby changing their chemical properties and application fields.

^{Product Features}

1）One uniform particle size: this is one of the most significant features of monodisperse polystyrene microspheres. The particle size distribution of the microsphere is very narrow, i. e., all microspheres are nearly identical in diameter, which ensures the accuracy and reproducibility of the experimental results.

2）Regular form: the microspheres are usually perfectly spherical, with a smooth surface and no obvious defects or irregular shapes. This regular shape facilitates its use in various application scenarios, such as as filling materials, standard particles, or chromatographic fillers.

3）Chemical stability: Polystyrene is a material with relatively stable chemical properties, so monodisperse polystyrene microspheres can maintain their physical and chemical properties in a variety of chemical environments. This allows them to be used in a wide range of conditions, including acids, bases, organic solvents, etc.

4）Physical stability: Microspheres are not easy to aggregate, settle or deform, and can maintain their morphology and performance for a long time. This physical stability is particularly important for applications requiring long-term stability, such as performance retention during long-term storage, transportation, and use.

5）Surface modifier: The surface of microspheres can be modified by chemical or physical methods to introduce various functional groups or coatings. This surface modifiability allows microspheres to have more functional and application potential, such as serving as drug carriers, catalyst carriers, biosensors, etc.

^{Application Fields}

1)    Optical field: it can be used to prepare high-resolution optical fibers and optical sensors.

2)    Biomedical field: used to prepare artificial nuclei, build artificial cell model, can also be used as drug carrier and diagnostic tool.

3)    Environmental protection field: it can be used for air pollution control, water pollution monitoring, etc.

4)    Other fields: in the electrochemical detection, catalyst, adsorbent, chromatography fillers, coatings and other fields are also applied.

^{Terms and Conditions}

Polystyrene microspheres are soluble in acetone, chloroform, tetrahydrofuran and other organic solvents, so they should not be mixed with the above reagents.

The working temperature should not exceed 100¡ãCto prevent the polystyrene microspheres from melting, deforming or sticking together.

Do not take them orally, if they accidentally splashes on the skin or eyes, rinse with plenty of water.
