Applications
PLAIN POLYMER
Uniformly sized Polystyrene (PS) and Poly (methyl methacrylate) (PMMA) microspheres have been found to have numerous applications in scientific research, diagnostics, electronics, pharmaceuticals, and nanotechnology. Examples of common applications are below:
- Size Standards
- Latex Agglutination Assays
- Solid Phase Immunoassays
- Markers
- Spacers in liquid crystal display (LCD)
- Purification and separation
- Ion-Exchange
PMMA microspheres are slightly more hydrophilic than polystyrene microspheres. This feature makes PMMA microspheres less likely to cause non-specific binding in biological applications than polystyrene beads. Additionally, PMMA is denser than polystyrene, which makes PMMA microspheres a bit easier to centrifuge in purification processes.
COLOR-DYED MICROSPHERES
Our featured color-dyed microspheres are available in two vibrantly dyed colors: blue and red. These colored microspheres are often used in lateral flow detection and latex agglutination tests. They are also frequently used as markers to label biomolecules. Carboxylated color microspheres allow for the covalent coupling of antibodies or antigens.
FLUORESCENT MICROSPHERES
Fluorescent microspheres are frequently used in imaging and diagnostic applications for the detection of binding events or signal enhancement. They can also be used for fluid tracing, fluid mechanics studies, cell tracking, phagocytosis studies, latex agglutination tests, fluorescence microscopy, and drug discovery research.
Fluorescent microspheres with surface functional groups allow for the covalent coupling of antigens and antibodies.
