Applications

The various functions of biological membranes are becoming the object of artificial simulation, and with the help of the selective permeability function of biological membranes, membrane structures with this function can be designed to filter and separate various kinds of water, thus purifying the water quality. An artificial membrane that can filter out salt from seawater has been fabricated for desalination of seawater, i.e., the pan-dialysis method.

In the field of bionics, scientists have experimented with artificial membranes, simulating biological membranes in the laboratory to build a semi-permeable membrane, using polymeric compounds. These techniques can be used in food processing and in medicine, where PC groups act as hydrophilic heads of membrane phospholipids in the outer layer of phospholipid bilayers. Scientists have shown that hemoglobin cells are anti-cancer because they have a PC group with a positive and negative charge. The research on PC motifs is currently increasing in various fields, and the results of this research are of great benefit to mankind.

Synthetic membrane materials are used to replace diseased organs in the human body for therapeutic purposes. For example, in the treatment of kidney function diseases, metabolic waste is filtered out of the patient's body by using hemodialysis membranes, and then clean blood is back into the patient's body. By making phospholipids into bilayer microspheres with antibodies on the outside, the wrapped drug can be transported to abnormal cells with specific antigens, and the membranes of the lipid microspheres can be fused with cell membranes for the purpose of treating various difficult diseases.
