The spherical particles can be used for SEM and TEM sample preparation, imaging studies and nanoscale morphology evaluation.

Atomic Force Microscopy

SPS90-10 can support AFM imaging, surface characterization and nanoscale measurement method development.

Laser Light-Scattering Research

The particles provide a defined polymer particle system for optical scattering, laser detection and nanoparticle concentration studies.

Colloid and Interface Science

SPS90-10 can be used to study colloidal stability, particle interactions, adsorption, aggregation and dispersion behavior.

Filtration and Membrane Evaluation

The 90 nm particles are suitable for membrane retention, nanoparticle filtration, particle transport and separation-efficiency studies.

Nanomaterial Method Development

Uniform polystyrene particles can support dilution, dispersion, recovery, imaging and quality-control procedure development.

Why Choose 90nm Polystyrene Microspheres?

The 90 nm particle diameter is suitable for research requiring a nanoscale and spherical model particle.

Compared with irregular powders, spherical microspheres provide more consistent geometry and help reduce the influence of particle shape during analytical testing.

Typical research areas include:

• Nanoparticle characterization

• Dispersion stability

• Aggregation behavior

• Optical response

• Surface adsorption

• Membrane retention

• Particle transport

Benefits of 5% Solid Content

SPS90-10 is supplied at 5% solids, providing a concentrated suspension for flexible laboratory use.

Users can dilute the particles according to the required working concentration. The concentrated format also reduces packaging volume and supports repeated experiments, pilot studies and bulk research projects.

Standard Polystyrene Surface

SPS90-10 has a standard polystyrene surface without added carboxyl or amino functional groups.

It is suitable for general particle research, physical adsorption studies and analytical method development.

For covalent biomolecule coupling, SHBC can also supply carboxyl, amino and other functionalized polystyrene microspheres.
