Monodisperse Polystyrene Microspheres

Product Overview

Monodisperse polystyrene microspheres (PS microspheres) are specialized high-polymer materials typically in an emulsion form, exhibiting a spherical shape. These microspheres have an extremely narrow particle size distribution, ensuring that all microspheres have nearly the same size, which gives them their monodispersity. The particle size can be controlled based on the preparation method and conditions. The surface of these microspheres can be easily chemically modified to introduce different functional groups, enabling them to exhibit various properties and functions for different applications.

Key Features

• Uniform Particle Size: The particle size distribution of these microspheres is very narrow, ensuring all microspheres have nearly the same diameter, which guarantees the accuracy and reproducibility of experimental results.
• Well-defined Shape: The microspheres are perfectly spherical with a smooth surface, free from significant defects, making them suitable for a wide range of applications.
• Chemical Stability: The chemical stability of polystyrene allows these microspheres to retain their physical and chemical properties in various chemical environments.
• Physical Stability: These microspheres are resistant to aggregation, settling, or deformation, maintaining stable performance during long-term storage, transportation, and use.
• Surface Modifiability: The surface of the microspheres can be chemically or physically modified to introduce more functions, such as serving as drug carriers, catalyst supports, etc.

Applications

• Optical Field: These microspheres are used to prepare high-resolution optical fibers and optical sensors.
• Biomedical Field: They are utilized in the preparation of artificial cell nuclei, construction of artificial cell models, and can also serve as drug carriers and diagnostic tools.
• Environmental Protection: These microspheres are used for air pollution control, water pollution monitoring, and other environmental protection applications.
• Other Fields: They are widely used in electrochemical detection, catalysts, adsorbents, chromatography fillers, coatings, and more.
