Light-Scattering Research

SPS300-10 provides a defined polymer particle system for laser scattering, optical response and particle-detection studies.

Latex Turbidimetric Immunoassays

The plain polystyrene surface can be evaluated for passive adsorption of antibodies or antigens in latex turbidimetric immunoassay development.

Latex Agglutination Tests

SPS300-10 may be used as a carrier particle for agglutination reagent research and diagnostic assay development.

Physical Protein Adsorption

The hydrophobic polystyrene surface supports the evaluation of non-covalent adsorption of proteins, antibodies, antigens and other biomolecules.

Colloid and Dispersion Research

The particles are suitable for studying colloidal stability, aggregation, particle interactions and surface adsorption.

Filtration and Membrane Studies

SPS300-10 can support membrane-retention, filtration-efficiency, particle-transport and separation studies.

Why Choose 300nm Polystyrene Microspheres?

The 300 nm diameter offers a practical balance between nanoscale particle behavior and strong optical response.

Its regular spherical morphology helps reduce particle-shape variation during comparative testing.

Typical research areas include:

• Immunoassay development

• Protein adsorption

• Latex agglutination

• Particle characterization

• Optical scattering

• Dispersion stability

• Membrane filtration

• Microscopy imaging

Standard Plain Polystyrene Surface

SPS300-10 has a non-functionalized polystyrene surface without added carboxyl or amino groups.

The plain surface is suitable for physical adsorption and general particle research. For controlled covalent biomolecule coupling, SHBC also supplies carboxyl, amino and other functionalized microspheres.

Benefits of 5% Solid Content

The concentrated 5% solids format provides flexible preparation for different applications.

Users can dilute the suspension to the required working concentration while reducing storage volume and supporting repeated tests, pilot projects and larger production requirements.
