Monodisperse polystyrene fluorescent microspheres are widely recognized for their uniform particle size distribution and stable fluorescence intensity, playing a vital role in various scientific and medical fields. These microspheres are invaluable in microscopy, cytometry, immunological assays, and high-throughput drug screening. They are also employed as drug delivery carriers, substrates for immobilized enzymes, and key diagnostic tools in bacterial and viral diagnostics. Furthermore, these fluorescent microspheres can be functionalized with amino or carboxyl groups on their surfaces, allowing for covalent bonding with proteins or other ligands. This capability supports complex biochemical experiments, including single-cell analysis, and expands their application in biomedical research.
