Microspheres

Microspheres are uniform, engineered particles used in diagnostics, drug delivery, assay development, immunoassays, and cell separation. They may be composed of polymers, silica, magnetic materials, or biodegradable substances. Their controlled size, surface functionality, and optical or magnetic properties make them essential tools in flow cytometry calibration, biomolecule immobilization, multiplex detection systems, and targeted therapeutic delivery. Magnetic microspheres enable efficient purification and sorting of nucleic acids, proteins, and cells. Fluorescent microspheres serve as stable standards in analytical instrumentation. With tunable characteristics, microspheres support a broad range of biomedical research and industrial applications requiring precision, reproducibility, and high binding capacity.
