Bionics will become the most important biotech in the 21st century because of its absorption of molecular biology. The famous American molecular biologist Stephen Wiyne White said. Recently, Xu Jian, a biomimetic material expert at the Institute of Chemistry at the Chinese Academy of Sciences, and his colleagues invented the “bionic lotus leaf†technology, which will be applied to the production of architectural coatings, apparel fabrics, and kitchenware panels that require dirt resistance. Caused widespread concern. A few days ago, the reporter interviewed Xu Jian, a researcher on biomimetic lotus leaf and other biomimetic materials. Bionic lotus leaves do not stick to the oil and the lotus leaves “sludge without siltâ€, and dewdrops can't stay above. Why does the lotus leaf not stick to mud and water? Xu Jian et al. analyzed the surface fine structure of the lotus leaf and found that there are many milky protrusions on the surface. These small particles that are invisible to the naked eye are the cause of the "Lotus Self-Cleaning Effect", which allows the lotus leaves to be free from contamination. So, Xu Jian and others imitated the surface structure of the lotus leaf and developed artificial bionic lotus leaf. The bionic lotus leaf is actually a kind of artificial polymer film. The film has the properties of being free from water and oil. At the same time, the bionic lotus leaf also has a "self-repairing" function similar to that of the lotus leaf, and the outermost surface of the bionic surface still retains the function of water-free and self-cleaning under the condition of being damaged. This study can be used to develop a new generation of bionic surface materials and coatings. The new "bionic lotus leaf film" can be used to make waterproof products such as waterproof film. Bionic lotus leaf paint wall will not stick dust. Biomimetic materials can degrade human beings for a long time to study the various properties of artificial materials. Although more and more new materials have been developed, chemical wastes and non-degradable garbage have been continuously produced, destroying the natural environment. Natural organisms have reached a near-perfect level during the long evolutionary process. There are not many and many materials produced by nature, and no waste of resources; more importantly, after the end of biological life, these natural materials can also be absorbed by other life and enter the natural cycle through death and regeneration. Therefore, mimicking the process of animal and plant production of various living body materials and inventing biodegradable materials that completely mimic biological structures is a goal pursued by scientists. At present, Canadian biotechnology researchers have developed a man-made spider silk that is particularly strong and can block bullets and is called "bio-steel." The greater advantage of this material is its degradable and environmentally friendly nature. Bringing out the human breast According to statistics, millions of people in the United States alone need surgery every year because of the loss or dysfunction of various tissues and organs. The annual cost is 40 billion US dollars. One of the existing treatments for severe organ damage is live transplantation, which involves transplanting other people's organs onto the patient. This brings two problems. One is the exclusionary effect. The other is that too few people supply organs. Many patients did not find suitable donors until they died. They had to leave the world with regret. Now, biomedical experts hope to use artificial biomimetic materials that mimic human tissues to artificially cultivate normal organs that the human body needs. In order to make artificial organs, biologists prepare a special “skeleton†as required. This “skeleton†is a biomimetic material that can be degraded. The degraded product is harmless to the human body and can provide a place for human cell growth. Biologists "seed" human cells on the "skeleton," and provided suitable growth factors to allow the cells to secrete the intercellular substance needed to build tissues or organs. For example, Harberstadt, a bioengineer at the Carolina Medical Center in the United States, designed and nurtured human breast tissue in an attempt to replace existing artificial breast implants. He took out fat cells from the patient's breast and planted it on a "skeleton" constructed of spongy sodium alginate. As a result, he grew into a very flexible human breast. After the breast grows, the sodium alginate "skeleton" can be in the human body. Degraded and absorbed by the body. Biomimetic materials enter the molecular level Xu Jian said that there are currently two methods for preparing biomimetic materials. One method is mainly through the preparation of a biologically similar structure or form of material that can replace natural materials such as biomimetic artificial bone materials, spider-like artificial fibers. The other is directly mimicking the unique features of the organism to obtain new materials that people need, such as bionic lotus leaf. The latter requires researchers to fully understand the molecular structure of the organism in order to learn nature from a more microscopic level. The second generation of “sharkskin swimsuits†launched this year by the world-famous swimwear manufacturer Spido Australia is using biomimetic fibers that mimic the unique functions of animals from a molecular structure. The secret of sharks being able to move forward in the water is the shark skin. They imitate the molecular structure of sharkskin to create a polymer-like artificial fiber that resembles a sharkskin, enabling new swimwear to significantly reduce water resistance.
