Magnetic particles have demonstrated their potential in the advancement of life sciences and biotechnlogy due to their unique physical and functional features. Ocean NanoTech's magnetic particles are an excellent choice since they offer the best balance of capacity, reproducibility, purity, and cost when used in various research and development applications. We use excellent size control techniques to provide a series ofsuperparamagnetic beads - MonoMag, HiSur, and SuperMag - with sizes ranging from 5 nm to 4.5 µm. They are provided in unmodified-form or modified with different functional groups or ligands for sample prep, or for capturing, separating, or purifying targets such as cells, proteins, antibodies, and nucleic acids. Other features include:
