Immunomagnetic beads (IMB) are a complex formed by binding molecules with immune activity, such as antibodies (or antigens), to the surface of magnetic particles through physical adsorption, chemical cross-linking, and other methods. It possesses both specificity of immune response and magnetic responsiveness. Magnetic particles, as carriers, are usually made of magnetic materials such as metals

Microspheres for drug delivery refer to spherical particles formed by the dissolution or dispersion of drugs in polymer matrix materials, with a particle size generally between 1-250 μm. They can be used for different administration routes such as intravenous injection, oral administration, local administration through the cavity, or subcutaneous implantation. Microsphere formulations can slowly release

Introduction to Streptavidin Magnetic Beads Streptavidin magnetic beads (SA beads for short) refer to magnetic microspheres with specific bioactive substances (streptavidin) modified on their surface.Streptavidin magnetic beads are a type of biological nanomagnetic beads with a surface functional group of streptavidin. They can specifically bind to biotin or biotin labeled molecules, thereby separating biotinylated molecules. The strong

PMMA微球又称甲基丙烯酸甲酯微球，是由MMA（甲基丙烯酸甲酯）单体经悬浮聚合而成的白色粉末颗粒，结构式如图1所示，是丙烯酸酯类中最重要、最常用的材料之一，也是合成领域中最优良、相对廉价的材料。

Fluorescent microspheres refer to particles with diameters ranging from nanometers to micrometers (0 Solid particles loaded with fluorescent substances within the range of 01-10 μ m, which can be excited to emit fluorescence by external energy stimulation. Lateral flow assay (LFA) has developed rapidly in recent years, with advantages such as simplicity, speed, independence from

Introduction to Magnetic Microspheres At present, the application of magnetic microspheres in biomedicine is represented by immunomagnetic microspheres, which have developed rapidly and have already been launched with many successful applications. Magnetic nanomaterials are an important component of magnetic microspheres, therefore the application of magnetic nanoparticles should also be considered. Preparation and Properties of Magnetic Nanomaterials The
