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

乳胶微球又称聚苯乙烯微球、PS微球等。聚苯乙烯微球是由苯乙烯自聚或苯乙烯与其他带有特定功能基团的单体共聚而成的聚合物微球的统称。聚苯乙烯微球表面具有较强的疏水性，可以与蛋白质或抗体进行物理吸附。此外，

乳胶微球是胶体尺寸范围内的球形颗粒，由聚苯乙烯等无定形聚合物形成。乳胶微球的粒径通常在1微米至100微米之间，但也可根据需要定制。乳胶微球的表面可以通过化学改性来改变其表面性质，例如表面

二氧化硅微球是一种重要的材料，是一种亲水性的乳白色悬浮液，表面的硅羟基可以与其他基团形成共价键，物理化学性质稳定，可耐高温达1000℃，在有机溶剂中保持稳定，但可溶解于强碱或HF溶液中
