Immobilization of enzymes is one promising method for improving enzyme performance such as stability, recyclability and reusability. However, studying suitable solid supports in enzyme immobilization continues to be one of the problems of preventing loss of enzymatic activity. Polyethersulfone (PES) and aminated PES (PES-NH 2) have been successfully synthesized as new materials for immobilization. The structure of the synthesized polymer was characterized by NMR, FTIR and MALDI - TOF. For use as a bioreactor to improve immobilized lipase performance, membranes based on PES and PES-NH 2 with different pore sizes (10-600 nm) were prepared.

Immobilization facilitates removal from product streams, enzyme recycling and cost reduction. Immobilized enzymes have a wide range of commercial uses, including the use of immobilized lactase (or beta-galactosidase) to produce lactose-reduced milk. Immobilization of the immobilized enzyme on an inert insoluble material has many advantages over enzymes in the free solution, including the ability to reuse the enzyme, which reduces the overall cost of the process. Immobilized enzymes can also be used in a continuous process, can be automated, are more stable when immobilized, and are therefore less likely to be denatured.

In order to be effective in the manufacturing process, it is necessary to maximize contact between the enzyme molecule and the substrate molecule. The solution can be mixed at an appropriate concentration or immobilization of the enzyme can be used. This involves attaching the enzyme to an inert surface such as plastic beads and then bringing the surface into contact with the substrate solution. Observe the shape of the cell that looks like two and associate the shape with the function. With EM, you can see the ultrafine structure, confirm the adaptability of the organelle and show how it works. Fuel concept of eukaryotic cells evolved from prokaryotic cells such as 嵴, Grana, circular DNA, ribosome (internal symbiosis)

The flow cell is a glass surface, and a specific part (oligonucleotide) of DNA physically adheres to it. Since these oligonucleotides are complementary to the region of the adapter, the oligonucleotides "capture" the DNA to be sequenced and immobilize it on a glass slide. There are two types of fixed areas, one type A and the other type B (this becomes obvious). Next add single stranded DNA sample. When our DNA is added, the complementary regions bind to each other, but our DNA still does not physically bind to the cells. In order to solve this problem, DNA polymerase is added to initiate DNA replication. This means that our single stranded DNA becomes double stranded, one immobilized region binds to the cell and the other region is not immobilized. Isolation of the chain and running of the buffer on the cell, removing all unbound DNA, leaving only the DNA sequence we copied physically attached.
