Microspheres, as the name suggests, are small spherical particles in the micrometer range (1-1000 microns). They have various applications in medicine and life sciences, such as drug delivery, tissue engineering, biosensors, medical imaging, etc. 01Classification It can be classified according to their composition, structure, and function. Some common types include: Polymer Microspheres: They are made […]

Introduction to Chemiluminescent Magnetic Beads Chemiluminescent magnetic beads are a type of sandwich structure magnetic beads that contain a porous polymer core, which is coated with special polymer materials to obtain specific surface properties. Magnetic materials are filled in the gaps between the two, which can enable the microspheres to achieve greater buoyancy and uniform

Fluorescent microspheres are obtained by post dyeing latex microspheres, with fluorescent dyes embedded inside the microspheres. The fluorescence signal is stable and will not leak. Therefore, there is no need to worry about changes in fluorescence intensity caused by dye leakage, nor about the impact of dyes on the crosslinking of microspheres and proteins. SHBC

SHBC colored microspheres are obtained by dyeing latex white microspheres, filled with nearly 20% oil soluble dyes in the matrix inside the microspheres. The color is bright and stable, which can present different color bands for different detection items of the same test strip and solve the problem of mutual interference when multiple items are

SHBC latex microspheres (50nm-400nm) can be applied in particle enhanced immunoturbidimetry, an improved immunoturbidimetric analysis method based on polyclonal antibodies. Genetic engineering methods are used to combine antibodies with latex particles, and when antigen antibodies combine, an antigen antibody latex microparticle complex is formed, enhancing reaction absorbance. Solid phase immunoassay, latex agglutination test, and microsphere

Photonic crystals (Photonic Crystal) was founded in 1987 by S. John and E. YablonovitchProposed independently, it is an artificial microstructure formed by the periodic arrangement of media with different refractive indices. Photonic crystals are photonic bandgap materials, and from the perspective of material structure, photonic crystals are a class of artificially designed and manufactured crystals with periodic dielectric structures at the

The history of single cell sequencing Single cell sequencing (SCS) technology refers to the sequencing of the genetic information carried by cells at the level of a single cell, aiming to obtain gene sequences, transcripts, proteins and epigenetic information of a certain cell type and conduct the integrated analysis. It has been widely used in

A lateral flow test (LFT),[1] also known as a lateral flow device (LFD), lateral flow immunochromatographic assay, or rapid test, is a simple device intended to detect the presence of a target substance in a liquid sample without the need for specialized and costly equipment. LFTs are widely used in medical diagnostics in the home,
Time-resolved fluorescence beads, as a special type of functional microspheres, are polystyrene microspheres internally embedded with complexes of rare earth ions. The rare earth ions commonly used for internal embedding include Eu3+, Tb3+, Sm3+, and Dy3+. When these rare earth ions form complexes with certain ligands such as β-diketones and aromatic amines, they can absorb
