Clothing.
Adding nanoparticles to textile and chemical fiber products can deodorize and sterilize. Although chemical fiber cloth is strong, it has annoying static phenomenon, which can be eliminated by adding a small amount of metal nanoparticles.
Edible aspect
Using nano-materials, refrigerators can resist bacteria. Sterile tableware and aseptic food packaging products made of nano-materials have come out. By using nano-powder, wastewater can be completely turned into clean water, which fully meets the drinking standards. Nano food is delicious and healthy.
Residential aspect
The application of nanotechnology can improve the washability of wall coatings by 10 times. Self-cleaning glass and self-cleaning tiles can be made by coating nano-thin layers on the surfaces of glass and tiles without scrubbing at all. Building materials containing nanoparticles can also absorb ultraviolet rays harmful to human body.
Nanorobot, nanorobot is the most attractive content in nanobiology. The first generation of nano-robot is an organic combination of biological system and mechanical system. This nano-robot can be injected into human blood vessels for health examination and disease treatment. Nano-robots can also be used to repair human organs, perform cosmetic surgery, remove harmful DNA from genes, or install normal DNA in genes to make the body run normally. Nanomaterials in transportation can improve the performance of vehicles. Nano-ceramics are expected to become ideal materials for engine parts such as automobiles, ships and airplanes, which can greatly improve the efficiency, working life and reliability of engines. Nanosatellites can provide drivers with traffic information at any time to help them drive safely.
Nano-catalysis, natural gas is a clean energy with high quality and high efficiency, and its main component is methane. Its selective activation and directional transformation is a difficult problem in the field of catalysis. Nano-catalysts developed by Chinese scientists can directly and efficiently convert methane into organic molecules such as ethylene, reducing pollution and energy consumption and improving energy utilization.
Traffic aspect
Nanomaterials can improve the performance of vehicles. Nano-ceramics are expected to become ideal materials for engine parts such as automobiles, ships and airplanes, which can greatly improve the efficiency, working life and reliability of engines.

Medical aspects
The micro drug delivery device made of nanotechnology can carry a certain dose of drugs and reach the focus accurately under the guidance of electromagnetic signals in vitro, which can effectively play a therapeutic role and reduce the adverse reactions of drugs. Micro robots made of nano-materials are smaller than red blood cells. By injecting them into patients' blood vessels, cerebral vascular thrombosis can be dredged. Remove fat and deposits from heart arteries, and also "chew" stones in the urinary system. Nanotechnology will be a good helper for a healthy life. The application prospect of nanotechnology is very broad, and the economic benefit is very huge. American authorities predict that the nanotechnology market will reach144 billion dollars in 20 10, and the application of nanotechnology will far exceed the computer industry in the future. Nano-composite, modification of plastics, rubber and fiber, design and application of nano-functional coating materials will inject new high-tech content into traditional production and products. Experts pointed out that a "material revolution" triggered by nanotechnology will inevitably occur in the fields of textiles, building materials, chemicals, petroleum, automobiles, military equipment and communication equipment. At present, nearly 65,438+000 companies in China have registered nanomaterials and nanotechnology, and more than 65,438+00 production lines for nanomaterials and nanotechnology have been established. Nano-fabrics and clothing have been mass-produced, such as computer work clothes, anti-static clothes, anti-ultraviolet clothes and so on. The new coating with nanotechnology not only improves the washability by more than ten times, but also is nontoxic, harmless and odorless. Nanotechnology is improving and improving people's quality of life. At present, many countries have made relevant plans and invested huge sums of money to seize the strategic highland of nanotechnology. The emergence of every new technology seems to contain infinite possibilities, especially nano-robots have unlimited application prospects. It won't be long before the magical nano-robots with molecular size will continue to enter human daily life. Professor Zhou Haizhong, a famous scholar in China, predicted in the article on robots published in 1990 that by the middle of the 20th century, nano-robots would completely change human labor and lifestyle.
Early detection of diseases and nano-drugs, nano-materials are widely used in the pharmaceutical industry because of their unique properties. For example, according to the fluorescence effect of quantum dots, the magnetic effect of magnetic nanomaterials, the adsorption effect of nanomaterials and so on. The sensitivity of detection can be greatly improved, which is beneficial to early detection of diseases. As a drug carrier, nanoparticles have the advantages of high targeting, controlled drug release, improved drug dissolution and absorption rate. Some nano-materials have also been proved to be efficient new drugs.
Nano-memory, scientists predict that in the near future, a cube-sized memory can hold the paper materials equivalent to 100 of the Library of Congress, and make unremitting efforts to this end. Chinese scientists put forward the design structure of the principle device of nano-ring magnetic random access memory, and prepared a new demonstration device of the principle of nano-ring magnetic random access memory. This design is expected to become one of the core technologies of the next generation of magnetic random access memory devices.
Nano-green printing manufacturing technology utilizes the controllable hydrophilic/lipophilic characteristics of nano-functional materials and combines with digital technology, and China scientists have developed a pollution-free green plate-making technology. This new technology eliminates the pollution of printing plate making from the source, and the cost is lower than that of traditional technology, and the printing effect is better. In addition to the traditional printing field, nano-materials can also be used in printed circuit boards.
