What is a Magnetic beads?

Magnetic beads are small spherical particles made from magnetic materials—primarily iron oxide-based magnetic nanoparticles. These beads are widely used in fields such as biology, chemistry, and medicine due to their ability to be manipulated by magnetic fields. They are commonly employed to quickly and selectively separate and concentrate target substances.

The surface of magnetic beads is often functionalized to bind specific molecules, such as antibodies, DNA, or enzymes. These functionalized beads can react selectively with target substances and be easily collected using a magnet. This technique enables efficient extraction of specific components from complex samples.

Main Features:
✅ Non-contact manipulation:
Can be handled remotely using external magnetic fields.
✅ Time and labor saving:
Faster and more efficient compared to traditional methods like centrifugation.
✅ Reusable:
Some types of beads can be washed and reused.

Application of Magnetic beads

✅ DNA/RNA extraction:
Used in molecular biology to isolate high-purity nucleic acids.
✅ Protein purification:
Beads functionalized with specific antibodies or enzymes are used to collect target proteins.
✅ Cell separation:
Antibodies attached to beads bind to cell surface markers for selective separation.
✅ Diagnostics:
Detect and recover pathogens or biomarkers in body fluids for disease diagnosis and research.
