Explanation

The process of binding or isolating the active substance in the same phase, separating it from the whole phase, separating sweat, and exchanging with substances (molecules, ions, etc.) outside the phase. immobilization methods mainly include: non covalent combination method, such as physical adsorption, ion combination method, etc; Covalent combination methods, such as crosslinking method and embedding method (microcapsule method, grid method, etc.). Immobilized materials (carriers) include natural or synthetic materials, such as polysaccharide, protein, ceramics, polyester, polyamide, nylon resin, alginate, chitosan, etc. In a broad sense, the assimilated substances include gas, liquid and homologous substances: in the field of biomedicine, there are mainly soluble enzymes, eggs, tissues and cells. "immobilization has the advantages of improved product activity, increased stability, use in harsh environments, storage and service life extension.
