Fluorescent Magnetic Microspheres

Product Introduction:
Fluorescent magnetic microspheres are specialized particles that merge the characteristics of fluorescence and magnetism. This design allows the particles to be manipulated and separated using magnetic fields, while the fluorescent dyes facilitate visualization and tracking under fluorescence microscopy. Due to their dual functionality, these microspheres find applications in a variety of biomedical fields, including targeted drug delivery, diagnostic assays, cell separation, and molecular imaging.

Our Products

Alfa Chemistry is capable of preparing fluorescent magnetic microspheres with different structures, sizes, fluorescent colors, and surface functional groups. The interior of these versatile microspheres is embedded with fluorescent dyes or fluorescent substances, which can emit fluorescence at specific wavelengths after excitation. In addition, our microspheres are also embedded with magnetic materials, which have excellent magnetic responsiveness. You can control the movement, separation, and recovery of the microspheres through an external magnetic field.

According to customer needs, our products can be equipped with different surface functional groups to facilitate the attachment of antibodies, ligands or other biomolecules. This customization enhances their utility in targeted drug delivery, immunoassays, cell sorting, and molecular imaging. If you are looking for high-quality fluorescent magnetic microspheres for your project, please do not hesitate to contact us immediately.

You Need to Know

Our products need to be sealed and stored at 4 °C, do not freeze. Freezing may lead to irreversible agglomeration of microspheres, thereby reducing the performance of biological applications.
Before use, please shake well. After use, please ensure the bottle cap is tightly closed to prevent the microspheres from drying out.
Our products are for scientific research use only and should not be used for other purposes.
