Uniform polystyrene microspheres are widely used in various scientific and industrial applications due to their consistent size and shape.

In biomedical research, they serve as calibration standards for flow cytometry and particle analyzers, ensuring accurate measurements. They are also employed in drug delivery systems, where their uniform size allows for controlled release of therapeutic agents.

In diagnostics, these microspheres are used as carriers for antibodies or antigens in immunoassays, enhancing the sensitivity and specificity of tests. They are also utilized in the development of biosensors for detecting biomolecules.

In material science, uniform polystyrene microspheres act as templates for creating porous materials and nanostructures. They are also used in coatings and paints to improve texture and finish.

In chromatography, they function as stationary phases, providing high resolution and efficiency in separating complex mixtures.

Overall, their uniformity and versatility make them essential in advancing research and technology across multiple fields.
