Foreign media reports, scientists in the United States and Japan jointly develop a smoothing gel like material objects, can be used to create new artificial joints, contact lens and so on.

This material is a hydrogel, the name suggests it is mainly made of water, but it has a very strong elastic. The latest study involved the National Institute of Standards and Technology (NIST) scientist Li Wu Wen (phonetic) said, "most white gelatin hydrogel is like a touch it will broken into many small pieces. However, our newly developed This gel is very strong pressure and flexible, you can squeeze any of it, it will remain smooth and flexible. "

Production of such hydrogels low raw material prices, which is composed of two polymers together. Filled with solid material a polymer with a second no-load solid liquid polymer material together with adhesive, if the polymer material is full of cracks in solid, liquid polymer will flow into and fill cracks.

Clear, transparent hydrogel, as smooth as cartilage, is used to create bionic joint material to improve the current performance. In addition, a number of hydrogel materials more than the current flexibility and abrasion resistance. WU Li-Wen said, "It is more shock absorption than other materials."

It is understood that in 2003, Hokkaido University researchers moderate overdosage Jian-Ping Gong in the laboratory to jointly conduct the study. Because of this built-protein hydrogel, it can also be used to manufacture contact lenses and artificial cornea and other areas.

This hydrogel used in animal experiments has been demonstrated to have great availability, but not for conducting clinical trials to assess the material in the value of human experimentation in the future. Hydrogel material in the study, Stanford University scientists Cotte Frank says, "It is a very good material is highly ductile. Hydrogel nature of this tissue compared with that in the future study can potentially be used to replace human tissue. "Currently, the study published in the March meeting of the American Physical Society meeting.
