Non-Functionalized Colloidal Polystyrene Nanospheres
 

  • CV< 3% from all nanospheres from 100 nm - 2000 nm.

  • Roundness > 0.980

  • Non-cross-linked by default with cross-linking options available upon request.

  • Sodium azide can be added as an antimicrobial agent upon request.

  • Surface Chemistry:
    Non-functionalized or carboxyl-terminated (-COOH)
    Other functional groups are available upon request.

  • Provided in Milli-Q water without any surfactants or ions.

  • Concentrations available: 10 - 300 mg/ml (i.e. 1 - 30% w/v).

Zeta Potential Measurement Results

Alpha Nanotech Polystyrene Nanoparticles

The preparation process for this product is mature and stable. Each batch of products is verified by various precision instruments such as high-resolution transmission electron microscopy, field emission scanning electron microscopy, particle size analyzer, and ultraviolet-visible spectroscopy. The series of monodisperse microspheres have high sphericity, strictly monodisperse particle size, small coefficient of variation and stable physical and chemical properties. Our polystyrene nanoparticles have nearly perfect sphericity and a narrow particle size distribution. These nanospheres have extremely stable physicochemical properties, are easy to store, and have good stability. The surface of the carboxylated spheres is rich in carboxylic functional groups and is easy to functionalize. The applications of these monodisperse polystyrene nanoparticles include the synthesis of the ordered materials, biomedical tests, particle size standards, and column packing.
